Test Analysis of Friction Couples With Solid Lubricant Coatings under Ground–Space Conditions and Prediction of Tribological Characteristics

As a result of an analysis of the literature data on ground–space tribological tests of friction couples with solid lubricant coating (SLC) ARSRI PP 212, the dependences for evaluating the starting antifriction characteristics have been determined. The wear life and coefficient of friction have been compared. According to results, calculation algorithms of tribological characteristics of friction couples with SLC for considered operational conditions have been developed and implemented.
