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 for example automobile components.
  • a friction modifier such as for example automobile components.
  • DLC coatings are also known to perform a second function which is to protect coatings against wear.
  • Such an additive is advantageously MoDTC which, in a hot rubbing contact, reacts chemically to give rise to the formation of compounds of the MoS 2 type perfectly known by a person skilled in the art to act as a solid lubricant.
  • the invention therefore resides in the combination of the effects of chromium nitride and MoDTC making it possible to significantly reduce the coefficient of friction, without however altering the hardness.
  • the invention relates to a system comprising two friction parts and a lubricated medium comprising a friction modifier between the two parts, the friction modifier being MoDTC, a coating being applied to one of the parts, and the other piece being steel.
  • the coating is chromium nitride applied to a external surface of the part, which presents an NaCl type crystallization whose microhardness is 1800 +/- 200 HV.
  • Friction tests were carried out in order to evaluate the behavior in a lubricated medium comprising a MoDTC friction modifier, of a DLC coating and of a chromium nitride coating, recalling, in a perfectly known manner, that in the case of a DLC coating, in order to reinforce its mechanical resistance, an underlayer, for example of chromium nitride, can be deposited.
  • an underlayer for example of chromium nitride
  • All the layers comprise a coating of chromium nitride produced by magnetron reactive sputtering.
  • the first step is to clean the steel specimens, which are then positioned on supports placed in the vacuum deposition chamber.
  • the interior of the machine and the parts to be coated are heated to a temperature of 150°C for 2 hours, in order to degas the parts and the machine. deposit.
  • the parts are subjected to ion pickling in an argon atmosphere, the purpose of which is to eliminate the thin layers of natural oxide and thus allow 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 is controlled by an optical measurement of the Cr emission in the plasma, so that the deposit contains 40+/-5 atomic % nitrogen.
  • a deposit of CrN is obtained exhibiting fcc crystallization of the NaCl type, the microhardness of which is 1800+/-200 Hv.
  • an aC:H type DLC coating is deposited by the PACVD technique, by cracking a hydrocarbon in a plasma, here, acetylene.
  • DCX-1 the final deposition of an aC-type layer is carried out by magnetron cathodic sputtering of a graphite target.
  • DCX-2 a plasma of pure oxygen is generated and the deposit is bombarded with 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 an Ra level of 0.02 ⁇ m.
  • the ball is made of 100Cr6 steel and has a diameter of 10 mm.
  • the coatings are applied to the ball.
  • the load applied to the ball is 10N, which gives a Hertzian contact diameter of 140 ⁇ m and an average pressure of 0.68 GPa.
  • the ball is animated by an alternating movement, the stroke of which is 10 mm.
  • the sliding velocity follows a sine-like profile, the mean value of which is 3.5 cm/s.
  • the test is carried out for a period of 15,000 cycles at a temperature of 110°C.
  • the conditions of sliding speed, pressure and temperature are such that the friction reducing additive reacts to fulfill its role.
  • the ball is observed and the diameter of the friction mark or wear mark is measured, from which the worn volume is calculated.
  • the attached graph ( figure 1 ) summarizes the average wear rates (worn volume reduced to the number of friction cycles). 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 trials.
  • the low coefficient of friction is mainly due to the friction reduction additive: MoDTC.
  • the DLC combination facing a steel friction antagonist, MoDTC is not compatible to achieve the two functions, namely, to resist wear on the one hand, and to obtain a coefficient of friction as low as possible on the other hand, whereas the claimed combination, namely, chromium nitride and MoDTC advantageously makes it possible to perform these two functions.
  • 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.
