- hard anodic coatings are composed with at least one of silicon or oxygen containing CrAl based system layer which is responsible for the increase in the degree of hardness and the in- crease in high temperature oxidation resistance, reducing the rate of abrasive and oxidation wear on cutting tools.
- a base ma ⁇ terial is first coated with a layer of Ti, Cr, Si or Al and an AlCrN hard layer is formed on top.

- Figure 7 High temperature wear-resistance ball-on-flat tests for aluminum-chromium-transition metal nitrides.
- the alloyed-AlCrN coatings were obtained using an industrial Balzers rapid coating system (RCS) machine.
- RCS Balzers rapid coating system
- This machine contains a low voltage arc discharge arrangement that allows for rapid heating and etching of the substrates which promotes high adhesion strengths.
- the apparatus is also equipped with six deposition sources which can be chosen from sputtering, cathodic arc and nano-dispersed arc jet sources. During the deposition, a negative bias voltage can be ap ⁇ plied to the substrate tools or components by using a fixed or a pulsed bias power supply.
- the previously cleaned workpieces were mounted, according to their di ⁇ ameter, either on double-rotating or, for diameters under 50 mm, on triple-rotating substrate carriers.
- Radiant heaters installed in the coating system heated up the workpieces to a temperature of about 500° C and, with a bias voltage of -100 to -200 V applied in an Ar- gon atmosphere at a pressure of 0.2 Pa, the workpieces sufaces were subjected to etch polishing with Ar-ions.
- the coating system is op ⁇ erated in a low pressure argon atmosphere utilizing at least two metal or metal alloy targets with at least temporarily addition of at least one reactive gas, applying at the substrate a negative voltage.
- a workpiece for the purpose of this invention, is being defined as having a body made from steel, high speed steel, hardmetal, cemented carbide, or any other suitable metal or ceramics.
- An example for a workpiece may be a tool for high temperature and/or dry tooling op ⁇ eration.
- tools are a cutting tool, a drill, a reamer, a broach, an insert, a hob, a mill, an endmill, a ball nose mill, a forming tool, a die casting mold, an injection mold, a stamping tool, a deep drawing tool, a forging die.
- the inven- tion can be applied to components, e. g.
- Such components comprise a tappet, a component of the valve train, a bucket tappet, a valve lever, a rocker arms, a pin, a piston pin, a roller follower pin, a bolt, a component of a fuel injection sys- tern, an injection needle, a gear, a pinion gear, a plunger, a piston ring.
- This listing is not terminating, further embodiments and ap ⁇ plications of the invention are possible and can be defined by a man skilled in the art.
- two of the six depo ⁇ sition sources were used to include a ductile TiN adhesion layer (around 0.3 urn thick) . Some of the experiments were repeated using miscellaneous adhesion layers like Ti, Cr and CrN and a similar per ⁇ formance was reached. The remaining four sources were utilized to deposit the main functional layer using customized sintered alumi ⁇ num-chromium-transitional metal targets and the ion plating deposi- tion process. Also, in some of the experiments, the main functional layer was co-deposited by combining an AlCr alloyed with a transi ⁇ tion metal and an AlCr containing silicon or boron.
- the sources were run at a power of 3.5 kw while the partial pressure of the nitrogen gas was maintained at approximately 3.5 Pa. Also, a substrate bias of -100V was applied during the deposition to enhance the ion bombardment process on the substrates. The deposi ⁇ tion time was always adjusted so that for all different coating com ⁇ positions, the thickness of the functional layer was around 4 ⁇ m.
- a total of ten customized compositions for the sintered targets were prepared. The aluminum atomic content for all the targets of all the compositions was fixed at 70%. One customized composition was com ⁇ posed of 30 at.
- % Cr eight customized compositions were composed of 25 at.% Cr and 5 at.% of Ti, Y, V, Nb, Mo, W, Si and B, respec ⁇ tively, and one composition was composed by 20 at.% Cr and 10 at.% Mo.
- the composition of the coatings correlated proportionally to the compositional analysis of the targets used (as it is shown in exam ⁇ ples 1 through 4) .
- the desired cubic crystal structure for an AlCrN coating containing small amounts of alloying elements is represented in figure 1.
- the NaCl (Bl) crystal structure is composed of anion nitrogen atoms 1 as well as of aluminum 2 and chromium 3 atoms that compete for the available cation positions.
- TM transition metal
- the lattice structure should get slightly distorted due to the dif- ference in atomic size and electronegativity.
- the amount of solid solution solubility would be limited because most transition metals have much lower capacity than chromium to stabilize the Bl structure in the presence of large amounts of aluminum atoms.
- solute TM atoms An ⁇ other factor affecting the solubility of solute TM atoms is the atomic radius difference between the TM and aluminum and chromium which should not be larger than 15% to achieve real solid solution strengthening. Indeed, depending on the nature of the transition metal alloy utilized solute atoms may restrict or not the movement of dislocations due to a resulting lattice distortion effect.
- the x-ray diffraction patterns and measured lattice parameters of a variety of AlCr-TM-N coatings are shown in figure 2. With the excep- tion of AlCrYN, the coatings showed a distinct Bl structure similar to the one expected for cubic AlCrN.
- the TM's are expected to have very small solubility due to their rela ⁇ tively large atomic size.
- the result is an amorphisa- tion of the microstructure, as shown in figure 2 for AlCrYN.
- Another effect of transition metal doping into an AlCrN Bl-structure can be the development of a (200) texture during film growth. This is what occurred, for instance, with the XRD pattern for AlCrNbN (figure 2) which shows a (200) preferred orientation in comparison to the more polycrystalline structure exhibited by pure AlCrN.
- the diffraction ratio QI (defined as the ratio of the dif ⁇ fraction intensity for the (200) plane with respect to the diffrac ⁇ tion intensity of the (111) plane) is shown for the AlCrN and for two AlCrMoN compositions.
- Increasing the molybdenum content in an AlCrN with a Bl-structure resulted on higher QI ratios.
- Controlling the texture and structure of a protective hard film is, technologi ⁇ cally, very desirable because the shape of the stress field varies significantly from one application to the next.
- the preferred orientation is predominantly controlled by the stoichiometry of the coatings.
- FIG. 4 The main structural arrangements that can be achieved by the compositions claimed in this invention are represented schematically in figure 4.
- Figure 4 (a) a poly ⁇ crystalline film composed of randomly oriented crystallites 6 are grown on top of a cemented carbide or a steel substrate 5.
- a second possibility is that a textured film is grown on a substrate 5, being the portion of crystallites oriented in a particular plane 8 is sev ⁇ eral factors greater than the disoriented ones 9.
- the third possi- ble microstructural arrangement (figure 4 (c) ) can be achieved by co-depositing a metalloid (either Si or B) leading to the formation of covalently bonded nitrides and to the creation of a separate amorphous or semi-crystalline phase 12 that surrounds the crystal ⁇ lites 11 with the resulting further increase in hardness.
- Hardness tests of the deposited hard layers were conducted with a Fischerscope HlOO depth-sensing microhardness instrument using a test load of 50 iriN.
- the residual stress was calculated by measuring the curvature of thin planar steel substrates by the three point bend test before and after the deposition.
- the plot in figure 5 shows the values obtained for a variety of AlCrXN composi ⁇ tions.
- Results in figure 5 indicate a beneficial strengthening ef ⁇ fect when low amounts of Nb, Mo and W are alloyed into AlCrN without any further increase in the residual stress of the coating. This surprising mechanical behavior can be in part explained by the mechanisms of solid solution hardening and the solubility of these elements into Bl-AlCrN observed in our experiments as explained above.
- Fig ⁇ ure 6 (a) illustrates the depth profile for a typical oxidation be ⁇ havior of a standard AlCrN coating with the formation of both chro- mium and aluminum oxides.
- AlCrNbN, AlCrMoN, and AlCrWN coatings showed a more optimal oxidation behav ⁇ ior (shown in figure 6(c)), where the amount of aluminum in the outer oxidized layer is similar to the aluminum content of the unoxidized part. This indicates the formation of stiff passive alu ⁇ minum oxides which can be very desirable in many cutting applica ⁇ tions.
- the wear resistance of the deposited layer was studied using a ball-on-disc test using a hard alumina ball counterface at high temperature and measuring the wear on the coating after a predetermined number of cycles.
- the wear rate of a variety of AlCrXN coatings is shown in comparison to TiAlN, AlTiN and AlCrN.
- the results also indicate that AlCrWN have the lowest wear of the set, even lower than the one corresponding to the pure AlCrN coating.
- the behavior of AlCr based coatings can be further improved by the al ⁇ loying of Nb, Mo, W or Ta.
- transition metals from group Vb and VIb being heavier than chromium.
- the best results can be reached when the atomic concentration of these ele ⁇ ments is between 2 and 10 percent of the metallic part, however an atomic concentration as low as 1 percent and as high as 20 percent would be possible.
- the presence of these alloying elements ulti ⁇ mate ly ensures good solubility, an increased hardness, and an opti ⁇ mal high temperature oxidation behavior. This decreases the abra ⁇ sive, diffusion and oxidational wear of coated mechanical components and cutting tools at high temperatures.
- the ac ⁇ tual invention refers to novel coatings and corresponding coated tools and components, having the coating the following global compo ⁇ sition:
- Example 1 shows the increased tool lifetime in meters of AlCrN based coatings compared to industrially used TiCN, TiAlN and AlTiN coat- ings.
- AlCrNbN, AlCrWN and AlCrMoN can be very beneficial when ap ⁇ plied to a ductile type substrate like high speed steel because they provide a surface of high hardness and an adequate adhesion.
- Example 2 Drilling Tool Steel
- Drill hole depth z 15 mm, blind hole Cooling: Emulsion 5%
- Example 2 shows the comparison of various AlCrXN coatings in HSS coated drills.
- Main tool life criterion is the standardized number of drilled holes over the coatings thickness until a predetermined maximum momentum is reached. The best coefficient of performance was shown by Nb,W and Mo alloyed AlCr-based coatings.
- Example 4 - Milling of austenitic stainless steel - roughing
- Example 4 shows the comparison in tool life of coated cemented car ⁇ bide end mills against stainless steel for four industrially used hard layer systems. Machining of stainless steel is a very difficult process due to its high toughness of this material, tendency to work harden and to adhere to the tool. The best results in terms of tool life were reached using AlCrNbN, AlCrMoN and AlCrWN coatings. This increased tool life could be related to both an increase in hardness at high temperatures and the good oxidation behavior exhibited with the use of Nb, Mo and W alloyed AlCrN systems, consequently increas ⁇ ing the wear resistance.
