“…Samples -pads 9x15x3 were made of AISI-201 steel coated with a high-entropy CuCrNiZrTi alloy (890 HV). The assessment of the wear of the pads was carried out according to the energy intensity of wear Im (mg•J -1 ), taking into account the determination of the work of friction forces at each of the stages of tribotechnical tests in accordance with the procedure described in [7]. In the case of obvious jumps in the resistance to rotation, at the second stage of the research, it was supposed to subject the systems of materials to repeated running-in with low load values of 45 N and 90 N with a holding time on each of them for 2 minutes.…”

The work carried out definitive tribotechnical tests of the systems of materials "CuCrNiZrTi - 85W90 - 40X", "CuCrNiZrTi - 85W90 - KCh50" to assess the nature of the manifestation of the effect of additive compositions (AC) ABRO GT-409 and POLYTRONTMC on adaptability to loading and lubrication modes parameters of adhesion properties when modeling shear on small samples. It was found that at the stage of running-in, the systems of materials operate stably with clearly pronounced tendencies to reduce the sliding resistance to a certain minimum, followed by its increase due to the influence of the AC components. ACs do not determine the effect of reducing the wear intensity in the investigated range of contact pressures, and a decrease in friction is caused by a decrease in shear resistance in the zones of contact interaction of protrusions and depressions of surface irregularities. A more significant effect on the decrease in the parameters of adhesion properties is exerted by the POLYTRONMTC 10% AC components, which cause the formation of secondary lubricant formations with denser structures at the interface of adhesion with metal surfaces and reduced resistance to movement within the formed cohesive bonds between them.
