This paper presents a comparative assessment of the tribotechnical characteristics of friction pairs with solid lubricant coatings (SLC) based on the MoS2 suspension application of VNII NP 212 and SLCCFUBMSIP deposited by the closed field unbalanced magnetron sputter ion plating (CFUBMSIP) of combined compositions MoS2+Ti, MoS2+Zr, MoS2+Cr , MoS2+W. It was established that under normal atmospheric conditions in the friction modes corresponding to the contact friction temperature of 157 °С, the life of SLCCFUBMSIP was 42.1% higher, and the coefficient of friction (ffr) was on average 2 times lower than that of SLC VNII NP 212. The average value of the life reduction coefficient for SLCCFUBMSIP during the transition from normal atmospheric conditions to water was 2.98. Under normal atmospheric conditions and in water, the SLCCFUBMSIP coefficient of friction was in the range of 0.02–0.04, and in an oil environment it ranged from 0.03 to 0.08. SLCCFUBMSIP based on pure MoS2 in normal atmospheric conditions, in water and oil was practically unusable.

A method was developed and implemented in regard to solid lubricating coatings (SLC) of the magnetron type for recalculating the specific wear intensity of the foreign-made friction pairs operating according to the ball-plane scheme of reverse and rotational motions to the linear wear intensity of friction interfaces with the SLC recommended for tribocouples according to the domestic standard. It was established that, compared with the VNII NP 212 SLC of suspension application, wear intensity of the combined SLC of magnetron application was higher: by 60–125 times for the W-S-C composition and by 40–63 times for the W-S-N composition. In the steady state, the W-S-N SLC had a higher friction coefficient than that of the VNII NP 212 SLC. In general, the W-S-C SLC antifriction characteristics were lower than those of the VNII NP 212 SLC, except for the D 4-38 SLC.
