Abstract
Description
- The present application relates to the preparation of fluorinated organic material. More specifically, the invention relates to the preparation of fluorinated organic material resulting from the friction-induced reaction of fluoride material with organic material.
-
- This reaction may provide a wear-protected surface. In one example, the fluorinated organic compound to be reacted may be Teflon® or polytetrafluoroethylene (PTFE). When added to, for example, a lubricant medium such as oil or grease, under heat and friction on a metal surface, the PTFE can be caused to chemically bond to the surface and protect the surface from wear. In these known methods, fluorinated organic compounds are always added to the metal surface to provide lubrication.
- Embodiments of the present invention provide a method for providing lubrication to a wear surface. A friction-induced in-situ reaction is used to generate an organo-fluoride material with anti-wear properties. The reactants may include fluoridated compounds such as metal fluorides, boron fluorides, silicon fluorides, and other non-metal fluoride moieties. The fluoridated compounds may be used alone or in combination and are reacted with an organic compound such as zinc dialkyldithiophosphate (ZDDP) or graphite.
- In other embodiments of the invention, organo-fluoride material formed by reacting fluoridated compounds with an organic compound may be bonded to a wear surface as a friction-induced reaction progresses.
- In yet another embodiment of the invention, a friction-driven reaction may be used to make a material with lubricating properties. In this embodiment, a suitable reaction medium such as a base oil is chosen. A friction-induced reaction between an organic compound and a fluoridated compound generates an organo-fluoride as the reaction product. The reaction product enhances the lubricating properties of the base oil in this embodiment.
-
FIGS. 1-3 are X-ray photoelectron spectroscopy (XPS) spectra showing the presence of organo-fluoride on worn surfaces. - A method disclosed herein forms a lubricated wear surface as one embodiment. A fluorinated organic compound or polymer (CF,) produced in an in-situ friction-induced reaction of small particles or molecules of a fluorinated compound with an organic compound, such as, for example, zinc dialkyldithiophosphate (ZDDP) or graphite. Organic compounds with weakly bonded alkyl and aryl groups are particularly suited for use in the present invention. The fluorinated organic compound forms on and/or in proximity to contact surfaces during friction and wear. In some embodiments, the fluorinated organic material works as a low-friction and wear-resistant film. The use of a metal fluoride, such as FeF3, with ZDDP creates fluorinated organic compounds that provide better lubrication than ZDDP alone can provide on the wear surface.
- The in-situ chemical reaction occurs with varieties of metal fluorides or other fluorine-containing species under a range of temperatures, contact stresses and relative speeds. This technology can be used in many different applications, such as in lubricants for automobile and aircraft engines or in other applications using moving components in need of lubrication. The method disclosed herein provides a novel means to alter the surface composition of metal, ceramics, plastics and the like through a friction-induced chemical reaction that produces functionally improved surface performance for industrial, commercial, domestic and other purposes. The invention may also be used to provide a desirable low-friction hydrophobic coating for some applications.
- It has been demonstrated in friction and wear tests that exposing fluoridated compounds such as metal fluorides (MF) in the presence of organics, such as ZDDP, to heat, friction and/or wear on a metal surface will produce fluorinated organic compounds (CFx) on the wear surface. This reaction can be illustrated as:
- The metal fluorides that may be used with the invention include, for example, iron fluoride, titanium fluoride, aluminum fluoride, tungsten fluoride, and combinations of various metal fluorides. The metal fluoride is consumed during the reaction, unlike a catalyst. The metal fluoride may retain some catalytic functions in some embodiments. Embodiments of the invention may employ other compounds such as boron fluorides, silicon fluorides, and other non-metal fluoride moieties. Below is a specific example using iron trifluoride (FeF3), which is converted to the difluoride moiety as the reaction progresses.
- In this example, the ZDDP reacts with the iron trifluoride under friction and wear conditions and is converted into a fluorinated organic material on the wear surface, such as the metal surface of an engine. This reaction has been observed to occur with the same results at varying loading pressures. The reaction illustrated above is not a normal degradation of the organic material (ZDDP). Instead, the iron tri-fluoride (FeF3) is consumed by the reaction with the organic material (ZDDP). The benefit of this reaction is that fluorinated organic materials are known lubricants, so the creation of fluorinated organic compounds on the wear surface provides thermal protection, wear resistance and lubrication directly at the point of highest need. In some embodiments, the wear surface material may be chosen to catalyze the reaction of the fluoride-containing material and the organic compound.
- It will be understood that other fluorine-containing compounds may be used in place of or in addition to ferric fluoride (FeF3), including, for example, aluminum trifluoride (AlF3), cryolite (Na3AlF6), zirconium tetrafluoride (ZrF4), titanium trifluoride (TiF3), titanium tetrafluoride (TiF4), tin fluoride (SnF2 and SnF4) and the like, and combinations thereof. Transition metal fluorides are used in certain embodiments. It will be further understood that a wide range of other organics may be used in place of ZDDP. Select inorganic compounds may be used in some embodiments, such as, for example, boron- or silicon-containing compounds.
- In the above-illustrated reaction, the MF and organics react under friction and/or heat to create new materials, fluorinated organic materials, that are known lubricants. In an exemplary embodiment, no fluorinated organic materials are present at the beginning of the reaction. However, in the presence of heat and/or friction during wear, fluorinated organic compounds are formed and act as a lubricant on the wear surface. In other embodiments, fluorinated organic compounds that have poor or no lubricant properties may be present at the beginning of the reaction and, in the presence of metal fluorides, these non-lubricant fluorinated organic compounds react under heat and friction to create other fluorinated organic materials that are good lubricants and wear-reducing agents. In some embodiments, heat is not required for reaction progression, and may occur at ambient temperatures and pressure. The use of a metal fluoride, such as FeF3, with ZDDP creates fluorinated organic compounds that provide better lubrication and wear protection than ZDDP alone can provide on the wear surface.
- The reactants may be brought into contact by dissolving them in an appropriate solvent or medium. Certain reactants may be in particle form and may be prepared for the reaction by generating a suspension of those particles. The particle size may vary in embodiments of the invention, but are sub-micron in size in a preferred embodiment. The fluorinated reactant compound is usually provided in a particle form, but the organic reactant compound may also be in particle form in some embodiments.
- The beneficial results of the present invention may be demonstrated by friction and wear tests using, for example, a ball-on-ring unidirectional sliding type Plint machine.
FIGS. 1-3 illustrate results of friction and wear tests that were conducted at approximately 25° C. for a range of contact pressures for iron fluoride (FeF3) in combination with ZDDP. No organo-fluorides were present at the start of the test. The spectra ofFIGS. 1-3 are XPS analyses of wear surfaces for ball surface pressures of 2.32, 2.93 and 3.68 GPa, respectively. - Two distinct F1s peaks appear in each FIGURE. The peaks that at approximately 690 eV (101, 201, 301) are identified as fluorine bound to carbon, as found in fluorinated organic materials, CFn (where n≧1). The peak at about 685.5 eV is identified as F bound to a metal, such as FeF3. The organo-fluorides (CFn) form in-situ on the wear surface and help to protect the surface from further wearing. Because no fluorinate organic compounds were present at the beginning of the wear test, it is apparent that the CFn is created from the interaction of the ZDDP and FeF3 on or near the metal surface. No fluorinated organic compounds are observed by conducting the same tests without ZDDP present.
- Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations can be made herein without departing from the invention as defined by the appended claims. Moreover, the scope of the present application is not intended to be limited to the particular embodiments of the process, machine, manufacture, composition of matter, means, methods and steps described in the specification. As one will readily appreciate from the disclosure, processes, machines, manufacture, compositions of matter, means, methods, or steps, presently existing or later to be developed that perform substantially the same function or achieve substantially the same result as the corresponding embodiments described herein may be utilized. Accordingly, the appended claims are intended to include within their scope such processes, machines, manufacture, compositions of matter, means, methods, or steps.
