COMPOSITIONS AND METHODS RELATING TO TRIBOLOGY

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims priority from United States provisional patent application No. 60/618,285, filed 12 October 2004, and United States provisional patent application No. 60/637,323, filed 16 December 2004, which are incorporated herein by reference in their entirety and for all their teachings and disclosures.

BACKGROUND

[0002] Generally speaking, "tribology" is the study of how to make things slippery and how to keep them that way for as long as possible, hi technical terms, tribology is often referred to as the study of design, friction, lubrication and wear of interactive surfaces in relative motion. Some of the problems that people studying tribology are facing include parasitic power loss, friction, wear and corrosion of mechanisms with direct surface-to- surface contact (e.g., metal-to-metal contact), particularly when such contact suffers from a lack of lubrication or otherwise has undesirable friction. Previous attempts at addressing such concerns have included a process known as "shot peening", for example as discussed in U.S. Patent Nos. 3,574,658; 3,754,976; 4,312,900; 4,753,094; 6,658,907; 6,694,798 and 6,790,295. (These and all other references set forth herein discuss certain systems, apparatus, methods and other information; all such references are incorporated herein by reference in their entirety and for all their teachings and disclosures, regardless of whether references may appear in this application.)

[0003] These prior systems, methods, etc., still leave open the need for improved methods, compositions, systems, etc., that reduce tribology-related concerns such as power loss, friction, lubrication, wear or corrosion. The present compositions, methods, systems, etc., reduce at least one of these concerns and provide other advantages.

SUMMARY

[0004] In certain aspects, the systems, compositions, methods, etc., herein provide significantly enhanced tribological properties to a target substrate such as metal, plastic, ceramic, wood, glass, etc., by bombarding or showering the target material with bombardment particles substantially saturated with a desirable lubricant composition comprising at least one primary lubricant such as a molybdenum disulphide (MoS₂) and at least one polymeric lubricant, such as polytetrafluoroethylene (PTFE), such that the lubricant composition imbeds into the surface of the target material (also called a target substrate). "Composition" indicates a combination of multiple substances into a mixture.

[0005] In other embodiments, the lubricant composition does not comprise a polymeric lubricant. For example, the lubricant composition can also be comprised of zinc sulfate heptahydrate, O₄SZn.7H₂O, which can be used in combination with another compound such as chromium metal powder. If desired, the composition can also include a polymeric component such as PTFE, either in an amount adequate to provide lubricity to the ultimate embedment composition and/or in an amount to help provide an anti¬ dumping property to the embedding composition prior to administration to the substrate, which may be less than an optimal lubricity amount. Such compositions may if desired primarily provide properties other than lubricity, such improved anticorrosive or antiwear properties, to the substrate.

[0006] It appears that this embedment process changes the molecular structure of the target material and creates a new, unique embedment composition in the surface of the target material. The embedment composition is not merely a layer of lubricant deposited on the surface of the target substrate but is rather the creation of a new composition, typically at least about 1 to 3, 4, 5, 6, 7, 8-10, 15 or more microns (μm) thick, having exceptionally good lubricity, corrosion resistance and/or other enhanced tribological properties.

[0007] Accordingly, in certain embodiments the embedment composition comprises the solid substrate and a suitable lubricant, such as the primary lubricant and the polymeric lubricant discussed below, mixed together. If desired, a layer of lubricant atop the substrate can be also deposited either during the embedment process or as a separate application of lubricant (in some embodiments, the embedding compositions can be used to make a surface layer of lubricant that does not involve making any embedment composition, including that such can be applied to materials with no embedment portion). Such additional lubricant layer made with lubricant plus bombardment particles may or may not be created with the same lubricant composition used to create the embedment composition. [0008] The bombardment process typically comprises the use of bombardment particles such as stainless steel shot, aluminum shot, glass beads, conch shell or steel or diamond grit that typically have been substantially completely coated (typically preferably at least about 90%, 95%, 98%, 99% or more, up to 100%, although less coverage can be provided if desired) with the lubricant composition that is suitable for embedding into the substrate to create the embedment composition. [0009] Accordingly, in some aspects the present invention comprises the lubricant composition itself, wherein the composition comprises at least about 55% (w/w) to about 99% (w/w) of at least one of primary lubricant, and about 3% (w/w) to about 55% (w/w) of at least one polymeric lubricant. Exemplary primary lubricants include metallic lubricants (typically dry although other matter states are also acceptable in some embodiments), graphite or boron nitride, for example molybdenum (IV) sulphide, molybdenum disulphide, molybdenum sulphide, molybdenum sulphide, molybdenum (IV) selenide, molybdenum selenide, tungsten (IV) sulphide, tungsten disulphide, tungsten sulphide, graphite, and boron nitride. Exemplary polymeric lubricants include PTFE (polytetrafluoroethylene), PFA (perfluoroalkoxy), ETFE (copolymer of ethylene and tetrafluoroethylene), FEP (fluorinated ethylene propylene copolymer), PTFE-S dry lubricant, PCTFE (polychlorotrifluoroethylene), and polyethylene. [00010] hi another aspect, the present innovations provide embedding compositions comprising bombardment particles in combination with the primary lubricant and the polymeric lubricant mixed together, such as the metallic dry lubricant, graphite or boron nitride, and/or the polymeric lubricants discussed elsewhere herein. Shot peening-type media are typically suitable for use as the bombardment particles. An exemplary list of suitable bombardment particles includes stainless steel shot, aluminum shot, corn cob, steel cut wire, ceramic, glass bead, aluminum oxide, silicon carbide, walnut shell, pecan shell, steel grit, soda bicarbonate, crushed glass, plastic, iron grit, slag and diamond grit. The type and size, etc., of the particle can be selected to enhance the embedding composition. For example, in some embodiments, increases in density of the chemical composition can be matched with increases in the mass and/or density of the particle. [00011] In other aspects, the present innovations provide systems, methods and the like for mixing suitable lubricants, not limited to those expressly discussed herein, with the bombardment particles and/or for bombarding the substrate material with such lubricants in a manner suitable to create an embedment layer. In certain embodiments, the embedment process is somewhat similar to shot peening processes and thus certain mixers, delivery systems, bombardment cabinets, etc., from the shot peening fields can be adapted for use in accordance with the innovations discussed herein, given the disclosure herein, but in certain preferred aspects the methods, etc., are performed using unique mixers, delivery systems, bombardment cabinets, etc., configured especially for the embedment processes herein.

[00012] In certain embodiments, the innovations discussed herein are conducted at different (typically lower) velocities than shot peening, for example from about 40-90 psi, and often for substantially shorter periods of time than the typical shot peening process, for example about 15 seconds to create an embedment composition in the surface of a 1.5 inch x 1.5 inch steel sample compared to up to about 8 hours for other lubrication technologies. Figure 1 depicts an example of an embedment process-treated steel sample next to an untreated sample. [00013] These and other aspects, features and embodiments are set forth within this application, including the following Detailed Description and drawings. Unless expressly stated otherwise or clear from the context, all embodiments, aspects, features, etc., can be mixed and matched, combined and permuted in any desired manner, hi addition, various references are set forth herein that discuss certain systems, apparatus, methods and other information; all such references are incorporated herein by reference in their entirety and for all their teachings and disclosures, regardless of where the references may appear in this application.

[00033] In certain aspects the present discussion is directed to compositions, methods, etc., that substantially improve the lubricity of target materials. The present innovations include creating an embedment composition within the surface of a target material, typically a solid material such as metal, plastic, ceramic, wood, glass, etc. The resulting surface, typically up to about 1-15 μm thick or more, has outstanding lubricating and corrosive resistance and/or other properties. In preferred embodiments, the compositions, etc., herein are environmentally safe, require no dangerous materials and are suitable for high- volume continual motion production. [00034] Rather than simply coating metal or other target surfaces (although, as noted above, making or applying such coatings can be effected if desired) the innovations herein create an entirely new embedment composition within the surface of the substrate, apparently by altering the molecular structure of the surface. Although not critical to the innovations, it is believed that the bombardment uses a form of energy to close exposed boundaries, actually changing the atomic structure of the surface while dispersing the chemical lubricant comρound(s) (which can be dry, resinous, liquid or otherwise as desired) into the substrate of the metal, typically also without destroying or losing the properties of those chemicals or the base (substrate) material. The bombardment compositions can have adequate kinetic energy to create elastic or inelastic collections with the substrate to provide a kneading of the substrate surface but preferably without disrupting the dimensional tolerances of the substrate. The impact can be enough to create a slight indentation, which can be smoothed by subsequent impacts by other particles. The bombardment particle may deposit the lubricating, etc., material before rebounding. [00035] Typical substrate materials are suitable for use in engines and engine components, ball bearings, high pressure fittings, tool and die, heavy duty automotive and truck products, chain and gear products, automobile and other mechanized racing, aerospace and military uses. [00036] The processes herein are suitable for use to make multiple substrate product combinations simultaneously or sequentially (e.g., treating gears and high pressure fittings at the same time) and can be adapted for different situations, for example by adapting the embedding composition by selecting specific embedding composition ratios or components, by selecting larger or smaller and more rounded or more angular bombardment particles, etc. The systems are highly suitable to provide uniform results for a variety of different parts and substrates over the course of extended periods of manufacturing time. [00037] It is a particular feature of certain embodiments that, unless desired to perform the processes otherwise, the dimensions of the substrate remain uniform during and after the embedment process: the process does not create any dimensional changes in the substrate, there is no build-up of surface material and the substrate's thickness does not vary significantly at edges, corners or bending points. The embedment compositions created using the innovations herein can be created to show no unstable movement due to heat (thermal migration), surface peeling (delamination) or chemical breakdown (decomposition).

[00038] The methods, etc., herein do not typically require (although such can be provided if desired for particular purpose) ultra high vacuum or evacuated chambers, emersion in inert gasses nor the use of toxic chemicals or high voltage equipment or clean rooms. The methods, etc., can be used with high-speed continuous motion production as well as batch or in-line processing or even one-by-one production such as for just-in-time inventory management. In some aspects the methods, etc., can be implemented within health and safety laws, without the use of toxic materials and can be managed without producing dangerous emissions or hazardous waste. The lubricant and bombardment particles, etc., that are used in the embedding process but are not actually incorporated into the embedment composition can be reclaimed or recycled. In certain embodiments, the methods, etc., can be incorporated into virtually any manufacturing process. This can be particularly useful where substrates are designed and/or manufactured having certain specific shapes and tolerances, then subjected to the innovative embedment processes, and then continued into further manufacturing processes, or into actual use, without any dimensional modifications to the substrates since the dimensions of the substrate have not been changed by the embedding process. [00039] In certain embodiments, the embedding processes can be run in simple blast cabinets using suction methods. Other bombardment methods and other cabinets or processing rooms (or lack thereof) can also be used as desired. [00040] Turning to a brief discussion of some of the figures that depict certain embodiments and parts of bombardment/embedment systems, Figure 2 depicts an air supply system 14 suitable for use with a bombardment system discussed herein. The system comprises a compressor 2 operably linked to a dryer 4 via a first conduit 8. The dryer 4 dries the air and/or the embedding compositions, and is operably linked via a second conduit 10 to a manifold 6. The manifold 6 is in turn linked via a second conduit 10 to a third conduit 30 to a blast or processing cabinet 28, where the embedding composition is applied to the substrate. The blast cabinet can be a small cabinet as in some of the drawings, and can comprise one or more nozzles to spray the embedding composition. The blast cabinet can also be a large cabinet, or even a room that forms the "cabinet", or otherwise be any suitable staging area for the embedment process to occur. The nozzle(s) can be fixed or moveable, for example via a control knob or the like for a small cabinet, or can be hand held in large cabinet, hand held in a large room wherein the room itself forms the "cabinet", etc. The nozzles can also be focused to provide a concentrated spray, or dispersive to provide a wide spray, or otherwise as desired.

[00041] Certain embodiments herein provide a particle kinematics system (PKS). The PKS is used to minimize settling of the bombardment particle composition or embedding composition while it is retained in a storage hopper or bin prior to delivery to a substrate in a blast cabinet for processing or bombardment. Such PKS reduces conglomeration of the bombardment materials and/or the coatings on the bombardment materials. Further, the PKS can act as a mixing phase, whether primary or secondary, for the delivery system. Further embodiments comprise recycleatory collection systems (RCS). The RCS can be used to reclaim residual bombardment particle mixtures that have been sprayed or otherwise delivered against a substrate in a processing cabinet. The systems preferably reclaim the bombardment particle mixtures without separating the elements of the mixture from each other (i.e., without separating the bombardment particles from the lubricant coating). The RCS typically further provides a stage, which can be an initial stage, of internal mixing for the delivery system. The RCS preferably captures and reclaims fine chemical particles in the air, and can if desired reclaim excess particles at the bottom of the processing cabinet. The RCS further provides advantages because it can reduce the amount of waste ultimately expelled or extracted from the system. The dried air can also be introduced into the RCS or other locations in the system. [00042] Figure 3 depicts an embodiment comprising a blast cabinet 28 with a RCS 32 attached to the right side. The RCS 32 is operably connected to the blast cabinet 28 by a connecting conduit 42 and includes a fan 34 located at the top to assist in the movement and processing of various materials. The RCS 32 feeds recaptured composition via a gravity feed tube 36 down to a hopper 38 containing a PKS 44 (shown in dotted line and discussed in more detail in other figures) comprising a spinning flanged wheel 40 and a deflector 46. In the embodiment shown, the blast cabinet 28 comprises a window 48 so that a user can view the process taking place, a plurality of control knobs to control, as desired, the positioning of sprayer 54, substrate 56 or stage 58. The sprayer 54 is fed by a pick up tube 52. The bombardment area 62 where embedment takes place is separated from hopper 38 by a divider 60. Of course, other combinations of the various elements can also be pursued if desired. For example, the fan can be omitted or located in other positions, the RCS 32 can be located in other positions including positions that do not use a gravity feed to the hopper, the sprayer, which may be a nozzle that provides a focused concentration spray, a wide-dispersion sprayer, or a plurality of sprayers or jets, can be fixed, movable by remote control, moveable by hand control, or even hand-held via a port in the side of the spray cabinet, etc.

[00043] Figure 4 depicts another embodiment of an RCS 32 attached to a blast cabinet 28. The RCS 32 is located up and to the left of the blast cabinet 28. The system also comprises a drain tube 64 comprising a valve 66 so that unused embedding composition can be easily removed from the hopper 38. If desired, a counterpressure mechanism can be provided so that the drain tube 64 can also function as a pick up tube to accept embedding composition from an external source(s), such as a pre-mixer, or a plurality of different component sources such as a reservoir of primary lubricant, a reservoir of polymeric lubricant, and a reservoir of bombardment particles. In such an embodiment, if desired, the system can further comprise one or more metering valves that control how much of each of the different components of the embedding composition are fed into the hopper 38. Of course, the embedding composition can also be fed into the system via one or more separate inlet ports if desired. [00044] Figure 5 depicts a cutaway side view of a funnel-shaped container portion 68 of the RCS 32. Initially, dust and other desired elements from the blast cabinet 28 are transmitted to the conductive container portion 68 having a side wall 70 and a conical bottom 72 via a connecting conduit 42 which, in certain embodiments, includes a joint 74 comprising a venturi valve 76 to intake air or other desired elements that can enhance the process. The collected dust is then sprayed into the interior of the container 68 and past one or more defusing/mixing fins 78 maintained inside the conductive RCS container 68. The container conducts the bombardment particle mixture dust and other elements from the dust connecting conduit 42 to a gravity feed tube 36 that transmits the material to the cabinet hopper or other desired location. In the embodiment shown, the RCS 32 also comprises an air intake filter housing 80 containing an air intake with a filter and a fan 34 that takes in air and mixes it with the collection mixture. If desired, the filter can also comprise a filtration mesh over the intake air filter.

[00045] Figure 6 depicts a part of a bombardment system set up to deliver embedment composition to a substrate The system comprises a compressor 2 operably linked to a dryer 4 via a first conduit 8. The dryer 4 dries the embedding compositions, and is operably linked via a second conduit 10 to a manifold 6. The manifold 6 is in turn linked via a return conduit 12, such as a hose, to the first conduit 8 between the compressor 2 and the dryer 4. This return connection permits constant pressurization and movement of the embedding composition before it is transmitted via a further conduit, an example of which is shown in Figure 2, conducts the embedding composition from these components to the blast cabinet or other desired staging area where the embedding composition is applied to the substrate.

[00046] Figure 7 depicts a part of the air supply system 14 discussed above, and comprises a wall manifold 26 comprising a housing 18 so that the air can be controlled and regulated via regulators 20 when it is supplied to one or more blast cabinet(s) (not shown) connected to the air supply system 14. Air can be taken into the regulator via valve 16, then transmitted via pipe 22 to regulators 20, when transmitted further the quick connect air port 24. In one embodiment, air compressor and dryer support 50 cfm @ 100 psi, and the system has a 120 gal tank for storage.

[00047] Figure 8 depicts a cutaway side view of one embodiment of a particle kinematic system 44 wherein a hopper 38 contains the bombardment or embedding composition 82, which in the embodiment shown is maintained at the bottom due to gravity. A low PSI mixing nozzle 84 sprays the embedding composition (the PSI can be varied as desired depending upon the bombardment particle composition). Nozzle 84 is fed by a feed tube 86 which functions as an air pressure input tube, and is also fed by a bombardment particle composition tube 88, which functions to uptake the bombardment particle composition from the bottom of the hopper. The nozzle 84 then sprays the composition against the underside of a concave plate 90. hi the embodiment depicted, a conical impact unit 92 is substantially centrally located in the concave plate 90, which conical impact unit 92 serves to spread out and separate the bombardment particle mixture before it returns to the bottom of the hopper 38. When the embedding composition 82 is needed for actual bombardment, the embedding composition 82 is taken through the pick up tube 52 shown at the right of the Figure. [00048] Figure 9 depicts a cutaway side view of a similar embodiment as in Figure 8, wherein the feed tube 82 comprises an intake port 94 to take up the composition 82, and the feed tube 82 is held to the bottom 98 of the hopper 38. hi both Figures 8 and 9, the spray apparatus can in some embodiments function like a bubbler. [00049] Figures 10-13 depict some further PKS embodiments comprising one or more flanged paddle wheels 40 or low PSI nozzles provided at the bottom of the hopper 38. For the flanged paddle wheels 40, the wheels spin and the paddles or flanges contact and throw or otherwise move the embedding composition 82 toward a deflector 46. If desired, the deflector can be an angled splitter 100 or a substantially spherical splitter 102, which splits and separates the mixture before it returns to the bottom of the hopper. As with the conical plates discussed earlier, one or more of each of the different particle kinematic system elements can be provided in the hopper(s), including mixing and matching different elements of the particle kinematic devices as desired. [00050] The chemicals are typically mixed prior to embedment, or after recapture from the blast cabinet. Figure 14 depicts a "V" mixer 104, which is one embodiment of a suitable mixer for substantially constantly mixing or agitating mixtures herein. As depicted, the "V" mixer 104 has a first arm 106 and a second arm 108, which contain the embedding composition 82. As can be seen, the "V" mixer 104 is rotated such that the embedding composition is split apart and mixed and re-combined. The mixture is mixed for any desired amount of time, typically until substantial saturation. Generally speaking, saturation is substantially complete coverage by the 2 or more chemicals of the lubricating composition over the bombardment particles, which can be verified by viewing samples under a microscope at different periods of time. Typically, at least 90%, 95%, 98%, 99% or better coverage of the bombardment particles is desired. [00051] The "V" mixer 104 can be rotated at any desired rate, for example about 0.3 - 3 revolutions per second. In one embodiment, the "V" mixer 104 can operate at 30 rpm with a 1/4 hp motor. The overall dimensions of the "V" mixer 104 can be: 46" long by 34" wide by 20" tall. The V chamber dimensions can be, for example, such that one side of the V is about 16-1/2" deep and the other side is 19" deep with an 80 degree separation angle between the sides, with each side having a diameter of 10" O.D. The size and dimensions can be modified as desired to suit the preferences of a given user and given system, composition, etc. A constant mixer such as the "V" mixer 104 in Figure 14 or a vortex mixer operating, for example, at 40-60 hertz, can be incorporated to provide new embedding composition to a blast cabinet, and/or it can be incorporated with a recirculation unit such as those discussed herein to transmit the mixture back into the cabinet. Once the mixture has entered/reentered the cabinet it can if desired then be re-mixed inside the bottom of the cabinet to improve the mixture.

[00052] As noted above, the various embodiments and elements, etc., herein can be combined and permuted as desired and variations on the elements can be also provided as desired. For example, the paddles on the rotating flanged mixers can be straight, can be curved to scoop material or otherwise configured as desired. Additionally, the splitters, if any, can be cone shaped, or pyramid shaped, spherical, or otherwise shaped to provide desired deflection and/or mixing, and the shape, composition, etc., of the various tubes, mixing or spraying nozzle(s), PSI, concave deflection plate(s), etc. can be varied. [00053] In some embodiments, a great deal of static electricity is created during prep and process, which creates a desire to insulate users from the static, hi one embodiment, a grounding strap can be attached to the cabinet and to the wrist of the user, to help reduce the discharge. A possible theory for the grounding strap is that it connects the user "in line" with the air supply so that the static is not jumping from the source to the user, hi some embodiments, the equipment is all linked together to obtain continuity to reduce static electricity.

[00054] In certain embodiments, the lubricating composition and the bombardment material are mixed outside the actual bombardment cabinet in a premixing step. Generally speaking, dumping the material into the blast cabinet without adequate mixing will not achieve the desired embedment composition. In other embodiments, for example where the blast cabinet has a mixing chamber (either separate from or combined with the bombardment chamber of the mixing cabinet), the individual components of the embedding composition can be provided separately to the blast cabinet, hi such embodiments, it may be preferred to run a mixer such as the bubblers and/or spinning wheels discussed herein before the composition is actually used for embedding. [00055] Once the lubricating composition and the bombardment particles are mixed together, the mixture can be put into a cabinet hopper or a storage bin. The mixture can then be drawn out of the hopper (or other device for providing the embedding composition for bombardment) through a hose, duct or other channel and then sprayed out of a nozzle or other outlet port where it is sprayed on to the target part where the embedment takes place. [00056] Embedding mixture that is not actually embedded (e.g., overspray) can then be collected, for example by allowing it to fall though a mesh grate (sifted) and then returned back to the storage hopper to be drawn through the system again. Airborne particles that are not incorporated into the embedment composition in the surface of the target can be collected by suitable methods, for example by force of air pressure being drawn upwards by vacuum into a secondary hopper with a filtration system, which filtered embedding composition can then be returned to the main hopper or other storage.

[00057] Turning to a further discussion of certain lubricant compositions suitable for creating the embedding compositions and ultimately the embedment compositions discussed herein, in certain embodiments the lubricant compositions comprise a) about 55% (w/w) to about 99% (w/w) of at least one of molybdenum (IV) sulphide, molybdenum disulphide (MoS₂), molybdenum sulphide, molybdenum (IV) selenide, molybdenum selenide, tungsten (IV) sulphide, tungsten disulphide, tungsten sulphide, graphite, or boron nitride; and b) about 3% (w/w) to about 55% (w/w) of at least one of polytetrafluoroethylene (PTFE), perfluoroalkoxy (PFA), ethylene-tetrafluoroethylene copolymers (ETFE), fluorinated ethylene propylene copolymer (FEP), PTFE-S dry lubricant, polychlorotrifluoroethylene (PCTFE), or polyethylene. [00058] In other embodiments, the compositions can comprise about 62% (w/w) to about 94% (w/w) of the compounds of a) and about 6% (w/w) to about 38% (w/w) of the compounds of b); about 75% (w/w) to about 85% (w/w) of the compounds of a) and about 15% (w/w) to about 25% (w/w) of the compounds of b). [00059] In certain embodiments, the compositions can comprise molybdenum disulfide (MoS₂) and polytetrafluroralethylene (PTFE), for example about 62% (w/w) to about 85% (w/w) MoS₂ and about 15% (w/w) to about 38% (w/w) of PTFE, or consist essentially of about 75% (w/w) to about 78% (w/w) MoS₂ and about 22% (w/w) to about 25% (w/w) of PTFE, or about 76.92% (w/w) MoS₂ and about 23.08% (w/w) PTFE. The MoS₂ can be technical grade MoS₂ and the PTFE can be in resin form, hi certain embodiments, the lubricating composition has a melting point of about 342 °F to 345 ⁰F, a specific gravity of about 2.1 to 2.3, and a density of about 5000-6000 kg/m^"3. [00060] The compositions can also comprise tungsten disulfide (WS₂) and polytetrafluroralethylene (PTFE)₅ for example about 69% (w/w) to about 94% (w/w) WS₂ and about 6% (w/w) to about 31% (w/w) of PTFE, and can consist essentially of about 82% (w/w) to about 85% (w/w) WS₂ and about 15% (w/w) to about 18% (w/w) of PTFE, to about 83.25% (w/w) WS₂ and about 16.75% (w/w) PTFE. Such compositions can, for example, have a melting point of about 1200-1300 ⁰F, a specific gravity of about 2.1 to 2.3, and a density of about 7000-8000 kg/m^"3. [00061] In another aspect, the embedding compositions can comprise components particularly suited for anticorrosion and/or anti-wear, such as zinc sulfate heptahydrate, chromium metal powder, tungsten sulfide (WS₂) and zinc sulfide heptahydrate. As can be seen, such compounds can also have good lubricity properties as well. [00062] hi certain embodiments, such compositions comprise zinc sulfate heptahydrate in powder form and chromium metal in powder form.

EXAMPLES EXAMPLE 1:

[00075] Summary:

[00076] A dynamometer test was performed on a Chevy 454 engine. The following particular components were treated with the embedment processes discussed herein: cam shaft, wrist pin, rocker arms, lifters, piston rings, and oil pump. The parts were treated with an embedding composition of 65% MoS₂ and 35% PTFE combined with a cast stainless steel shot SS 120 specification. Each piece was processed at a 70 to 90 degree angle and an about 3 inch distance from the spray nozzle at 90 PSI. Process time was 30 to 45 seconds for each surface area. A secondary sweep of the parts was performed at a 45 degree angle for 15 sec at 90 PSI for finishing effects. The primary metric for the test was engine torque (ft-lbs.). Horse power is a calculation based on torque output. Hp = (torque x rpm)/5250.

[00077] Engine torque was 5% higher than the baseline. Some observations during the test were cooler oil operating temperature, cool to the touch rocker arms, and higher torque. [00078] Results: [00079] After an initial warm up break-in period, which had numerous full throttle cycles to seat the piston rings to the cylinder wall, the valve covers were removed for internal rocker arm inspection. The warm up or "break in period" was part of the testing procedure and lasted approx. 20mins. The remainder of the test comprised approx. 2 hours of constant running with various rpm ranges, from 2500 to 5500 rpm. The rocker arms were cool enough to touch, which was highly unusual and never previously experienced by the particular testers during such a test procedure. Valve covers were reinstalled and test was resumed. During the test cycle the engine oil temperature did not exceed 138⁰F as compared to a normal baseline (control) of 15O⁰F. The engine was also generating more power than baseline (control) results.

[00080] Numerous data sweep collections were performed during the test for accurate and consistent data recovery. It is believed that the results would have been even more significant had oil with a lower viscosity been used. The fact that the oil temperature was running much lower than baseline caused it to be more viscous leading to more drag losses. Therefore the use of lower weight oil would have produced more torque and horsepower. However even with these factors there was a total increase in torque/horsepower of 5%. The engine was running at a cooler temperature than normal baseline, which indicates that there are less friction conditions, and it was generating more power and the cooler running condition would lend itself to less fuel consumption and greater longevity. Figures 15-17 depict graphs containing the results discussed in this Example.

EXAMPLE 2: [00081] Summary: [00082] A camshaft and lifter components were embedment treated in the same manner as the parts in Example 1. The test included a comparison of standard non-treated cam lobes and lifters in various combinations with treated cam lobes and lifters. The treated and non-treated parts were subjected to a consistent simulated engine speed with a significant pressure applied to the lifter in contact with the cam lobe. After a designated warm up period with standard pressures applied to each lifter, a predetermined extreme load was placed on the lifter. The cam lobe and lifter were run to failure. It was found that when at least the cam lobe, or both the cam lobe and lifter, were treated with the embedment process they lasted until the end of the test, which was about 90% longer than other combinations of treated or non-treated components. [00083] TEST METHODS:

[00084] There were two series of test runs for the purpose of comparison. The first series included a 16 lobe camshaft and four lifters in contact with lobes numbers 1, 5, 9, and 13. The camshaft was exposed to a standard shot peening preparation just prior to being treated with the embedment process. It should be noted that this shot peening preparation is standard to the industry and was consistent with those cam shafts currently sold in the market. Lobes 1 through 8 were left untreated. Lobes 9 through 16 were treated with the embedment process. Lifters numbered 1 and 13 were left untreated. Lifters numbered 5 and 9 were treated with the embedment process. Lifters numbered 1 and 5 were paired with untreated cam lobes. Lifters numbered 9 and 13 were paired with a embedment treated lobe. [00085] The test began with a warm up period. The cam / lifter set up was run at 6000 RPM for approximately 30 minutes with 270 pounds of pressure applied to the lifters. Immediately after the initial 30 minute break in period the apparatus was run an additional 30 minutes with 400 pounds of pressure applied to the lifters. This warm up phase is considered a standard in the industry with regard to cam shaft and lifter analysis. [00086] After the initial warm up period the apparatus was maintained at 6000 RPM, and 530 pounds of pressure was applied to each of the four lifters against the cam lobes. Position number one, which had an untreated cam lobe and an untreated lifter, ran 10 minutes before failure. Position number five, which had an untreated cam lobe and a treated lifter, ran 5 minutes before failure. Position number nine, which had a treated cam lobe and a treated lifter, ran 120 minutes without failure. Position number thirteen, which had a treated cam lobe and an untreated lifter, ran 120 minutes without failure. Table 1 below shows some results of this testing: Table 1 Test Series 1 ("UT" = untreated; "TR" = treated)

[00087] Figure 18 is a graph containing results discussed above in this Example.

[00088] A second series of tests included a 16 lobe cam shaft and eight lifters in contact with lobes numbers 1, 3, 5, 7, 9, 11, 13, and 15. The cam shaft was exposed to a standard shot peening preparation just prior to being treated with the embedment process. It should be noted that this shot peening preparation is standard to the industry and was consistent with those cam shafts currently sold in the market. Lobes 1 through 8 were left untreated. Lobes 9 through 16 were treated with the embedment process. Lifters numbered 1, 3, 13, and fifteen were left untreated. Lifters numbered 5, 7, 9, and 11 were treated with the embedment process. Lifters numbered 1, 3, 5, and 7 were paired with untreated cam lobes. Lifters numbered 9, 11, 13, and 15 were paired with a embedment treated lobe.

[00089] The test began with a warm up period. The cam / lifter set up was ran at 7000 RPM for approximately 30 minutes with 270 pounds of pressure applied to the lifters. Immediately after the initial 30 minute break in period the apparatus was run an additional 30 minutes with 400 pounds of pressure applied to the lifters. This warm up phase is considered a standard in the industry with regard to cam shaft and lifter analysis. [00090] After the initial warm up period the apparatus maintained 7000 RPM and 600 pounds of pressure was applied to each of the eight lifters against the cam lobes. Position number 1, which had an untreated cam lobe and an untreated lifter, ran 10 minutes before failure. Position number 3, which had an untreated cam lobe and an untreated lifter, ran 10 minutes before failure. Position number 5, which had an untreated cam lobe and a treated lifter, ran 5 minutes before failure. Position number 7, which had an untreated cam lobe and a treated lifter, ran 5 minutes before failure. This is also consistent with pin on disk data.

[00091] Position number 9, which had a treated cam lobe and a treated lifter, ran 120 minutes without failure. Position number 11, which had a treated cam lobe and a treated lifter, ran 120 minutes without failure. Position number 13, which had a treated cam lobe and an untreated lifter, ran 120 minutes without failure. Position number 15, which had a treated cam lobe and an untreated lifter, ran 120 minutes without failure. Table 2 below shows some results of this testing:

[00092] Figure 19 is a graph containing results discussed above in this Example. [00093] DISCUSSION:

[00094] The embedment process applied to the cam shaft and lifters comprises a chemical mixture applied to the surface of the metal via a pressurized stream of particulate which acts as a catalyst to create the chemical reaction used in the treatment of the metal. The embedment process alters the surface of the substrate creating an amorphous surface with increased lubricating properties. It should also be noted that prior to treatment with the embedment process, the cam shafts were subjected to shot peening treatment. This is considered a standard process in the industry. While bombardment is part of the delivery system for the embedment process, the prompt failure of the untreated cam lobes and lifters indicate superior results of the embedment process versus normal shot peening.

[00095] This test is considered to be a good measure of durability for the cam shaft and lifter mechanism. Typically the amount of pressure applied on the lifter to the cam lobe in the average engine is between 100 and 150 pounds. The application of 530 to 600 pounds of pressure run at a high RPM will exceed the typical real world scenario. [00096] As outlined in the test methodology, it was noted that when the cam lobe was treated with the embedment process the cam and lifter combination would last significantly longer than that of the untreated cam lobe. It should be noted that this test was ran only 120 minutes prior to being discontinued. The treated components may have run longer.

[00097] While the untreated cam lobe and lifter combination failed rapidly it is noted that a similar result was found with the treated lifter combined with an untreated cam lobe. Contrary to this was the findings that an untreated lifter with a treated cam lobe gave the same results as that of a treated cam lobe and treated lifter combination. The results indicate that the treatment of the larger surface area of the cam lobe versus the smaller contact area of the lifter enhances durability and performance.

EXAMPLE 3:

[00098] Several metallurgical samples were run utilizing a Pin-on-Disk tribo apparatus. Each sample was prepared according to ASTM standards. In pin-on-disk tribometry, a flat, a pin or a sphere is loaded onto the test sample with a precisely known weight. The pin is mounted on a stiff lever, designed as a frictionless force transducer. The deflection of the highly stiff elastic arm, without parasitic friction, insures a nearly fixed contact point and thus a stable position in the friction track. The friction coefficient is determined during the test by measuring the deflection of the elastic arm. Wear coefficients for the pin and disk material are calculated from the volume of material lost during the test. This simple method facilitates the study of friction and wear behavior of almost every solid state material combination with or without lubricant. Furthermore, the control of the test parameters such as speed, frequency, contact pressure and varying time, and the environmental parameters, temperature, humidity and lubrication allow a close reproduction to the real life conditions of practical wear situations. [00099] This test was set up to compare data from metallurgical samples of 316 stainless steel with and without embedment treatment that was the same as in Example 1. The data compared deflection of the elastic arm and over a period of time and the volume of material from the pin and disk lost during the test. Each test was set up with a substantial load of 35 N on the pin point tip. The tip was set at a fixed position while the sample was set into rotation at a speed of 25.00 cm/s with a radius of 4.99 mm. [000100] The first set of samples was run without the embedment application to establish a base parameter of readings. These samples exhibited a minimum coefficient of friction of -0.168 and a maximum coefficient of friction of 1.197. The mean average coefficient of friction was 0.491.

[000101] The second set of samples was run with the embedment application incorporated into the substrate material. These samples exhibited a minimum coefficient of friction of -0.032 and a maximum coefficient of friction of 1.220. The mean average coefficient of friction was 0.294.

[000102] A comparison of the data indicates that under similar conditions the embedment application when applied to the substrate surface lowered the coefficient of friction by 59.877% when compared to the base readings taken on the samples without the embedment application under similar conditions.

[000103] Figures 20-21 are graphs depicting results discussed above in this Example.

EXAMPLE 4:

[000104] Several metallurgical samples were run utilizing a linear tribo apparatus. Each sample was prepared according to ASTM standards. The Linear Tribometer reproduces the reciprocating motion typical of many real world mechanisms. Including calculating a friction coefficient for both forward and backward movements of the stroke, generating data on Hertzian pressure via its software package, and static partner and sample wear rates. The reciprocating technique is also very useful for studying the variation over time of the static coefficient of friction - as opposed to the kinetic coefficient measured with the Pin-on-Disk geometry. The maximum load is 46 N at frequencies up to 8 Hz (25Hz optional) with a stroke range up to 60 mm. [000105] This test was set up to compare data from metallurgical samples of 316 stainless steel with the embedment application, against samples without treatment. The data compares wear rates over a period of time. Each test was set up with a substantial load of 35 N on a pin point tip in order to maximize ware rates over time. The tip was set into a linear motion with an amplitude of 9.98 mm with a maximum linear speed of 15 cm/s.

[000106] The first set of samples was treated with the embedding application that was the same as in Example 1, and run under the fore-mentioned parameters. These samples showed an average failure rate of 573 sec under a 15 minute run duration. [000107] The second set of samples without the embedding application was run under the same parameters. These samples showed an average failure rate of 145.8 sec under a 15 minute run duration.

[000108] A comparison of samples shows that the embedment application when applied to the surface ran .77.554% longer than the samples without the embedment application under simulated conditions.

[000109] Figures 22-23 are graphs depicting results discussed above in this Example.

EXAMPLE 1:

[000110] Scratch-testing with a Micro Scratch Test apparatus is a comprehensive method of quantifying the adhesion properties of a wide range of coatings. The technique involves generating a controlled scratch with a diamond tip on the sample under test. The tip, for example a Rockwell C diamond or a sharp metal tip, is drawn across the coated surface under either a constant or progressive load. At a certain critical load the coating will start to fail. The critical loads are detected very precisely by means of an acoustic sensor attached to the indenter holder, the frictional force, penetration depth and by optical microscopy. Once known, the critical loads are used to quantify the adhesive properties of different film - substrate combinations. These parameters constitute a unique signature of the coating system under test. The data is acquired by a Pentium with real-time display of all the information. [000111] An initial sample with the embedment application was set up for a progressive linear scratch. The test started with a beginning load of 30 mN increasing to an end load of 20,000 mN. The load rate was set at 40054.44 mN/min. The indenter consisted of a Rockwell diamond with a radius of 20 μm. Complete delamination of the embedment application was found at a penetration depth of 67.85 μm and a load of 19,987.75 mN. This indicates very good adhesion properties of the embedment application. [000112] The same sample was subjected to a constant scratch test at a load maintained at 2,000 mN. The "Y" coordinates were adjusted to 12.205 mm. The AESensitivity was set at level 9 with a drag speed of 5.22 mm/min. A similar indenter was utilized, consisting of a Rockwell diamond with a radius of 20 (1 J.In). The coefficient of friction measured between 0.20 and 0.78 with a mean of 0.58. The normal force of2.000 mN remained constant throughout the duration of the test. While surface roughness was a factor in coefficient of friction variations, the overall procedure showed consistent uniformity of the substrate surface.
