Purpose: The paper presents the results of a study of the effect of vacuum technologies of formation of surface layers on pitting of associated elements in a lubricated, heavy-load rolling contact. Design/methodology/approach: Samples of 16MnCr5 vacuum-carburised steel, 100Cr6 bearing steel as well as elements of 100Cr6 steel with deposited coatings of titanium nitride (TiN) and chromium nitride (CrN) of various depths have been examined. The contact under examination was lubricated with RL 144 standard mineral oil with no additives. Findings: The study has shown that increase in a PVD coat depth is accompanied by decrease in the fatigue friction pair. Research limitations/implications: The elements after cutting-edge surface processing may have lower surface fatigue strength. It is one of the reasons for them not being used in lubricated friction parts of machines, especially high-performance ones. Originality/value: The study has shown a significant and varied effect on pitting of vacuum technologies of surface layer deposition in associated elements in concentrated rolling contact.
