Definitions
- the invention relates to the technical field of tribology in a lubricated medium.
- the invention relates to friction parts operating in a lubricated medium comprising a friction modifier, such as automobile components.
- DLC coatings are also known to fulfill a second function which is to protect the coatings against wear.
- Such an additive is advantageously MoDTC which, in a hot rubbing contact, reacts chemically to give rise to the formation of MoS 2 type compounds perfectly known to those skilled in the art to act as a solid lubricant.
- the invention thus lies in the combination of the effects of chromium nitride and MoDTC to significantly reduce the coefficient of friction, without impairing the hardness.
- Friction tests were performed to evaluate the behavior in a lubricated medium comprising a MoDTC friction modifier, a DLC coating and a chromium nitride coating, recalling, in a well-known manner, that in the In the case of a DLC coating, in order to reinforce its mechanical strength, it is possible to deposit an underlayer, for example, of chromium nitride.
- Table below shows the tests carried out on four coatings, namely, DCX- 0, DCX-1, DCX-2, DCX-3, the DCX-3 coating being in accordance with the invention.
- the set of layers comprises a coating of chromium nitride produced by magnetron reactive sputtering.
- the steel specimens are first cleaned, which are then positioned on supports placed in the vacuum deposition chamber.
- the inside of the machine and the parts to be coated are heated at a temperature of 150 ° C for 2 hours in order to degas the parts and the machine deposit.
- the pieces are subjected to an ionic etching in an argon atmosphere, the purpose of which is to remove the thin layers of natural oxide and thus allow a strong adhesion of the coating.
- the deposition of chromium nitride is obtained by reactive magnetron sputtering of a Cr target in an argon / nitrogen mixture.
- the nitrogen flow rate is slaved to an optical measurement of the emission of Cr in the plasma, so that the deposit contains 40 +/- 5 atomic% of nitrogen.
- a deposit of CrN exhibiting cfc crystallization of the NaCl type, the microhardness of which is 1800 +/- 200 Hv is obtained.
- a coating of DLC type aC: H by PACVD technique is deposited by cracking a hydrocarbon in a plasma, here acetylene.
- DCX-1 the final deposition of an aC-type layer by magnetron sputtering of a graphite target.
- DCX-2 a pure oxygen plasma is generated and the deposit is bombarded by ions from the plasma for 10 minutes, which makes it possible to modify the surface chemistry of the deposit.
- the plane consists of a steel specimen, polished to a Ra level of 0.02 ⁇ .
- the ball is made of steel
- the load applied on the ball is 10N, which gives a diameter
- the ball is animated by an alternating movement, whose race is
- the sliding speed follows a sinus-like profile, whose average value is 3.5 cm / s.
- the test is conducted for a period of 15,000 cycles at a temperature of 110.degree.
- the sliding speed, pressure and temperature conditions are such that the friction reducing additive reacts to fulfill its role.
- the attached graph ( Figure 1) summarizes the average wear rates (used volume based on the number of cycles of friction). For each coating, 3 tests were carried out, the average wear was calculated. The error bars represent, not an error, but the smallest value and the largest value for these 3 tests.
- the DCX-3 coating according to the invention has zero wear in test fm, the friction diameter is very slightly greater than the initial contact diameter.
- Chromium nitride has a hardness of the order of 1800 Hv.
- the low coefficient of friction is mainly due to the friction reduction additive: the MoDTC.
- the combination DLC facing a steel friction antagonist, MoDTC is not compatible to perform both functions, namely, resist wear on the one hand, and get a coefficient of friction as low as possible on the other hand, while the combination claimed, namely, chromium nitride and MoDTC advantageously allows these two functions to be performed.
- the invention also relates to the use of parts thus coated and working in a lubricated medium containing MoDTC in the automotive field, in particular for engines and gearboxes.
