    Abstract

    The results of a comparative study of the effect of a nanophase Ti–C–Mo–S coating on tribotechnical and mechanical properties of a VT6 (α+β)-titanium alloy in its coarse-grained and submicrocrystalline states are presented. To form the coating of a Ti–C–Mo–S chemical composition, use is made of a low-temperature magnetron-plasma deposition process at the substrate temperature not higher than 300°С. With a 1–1.3μm multi-component nanophase coating, the friction coefficient in a friction pair of the like grain structure (submicrocrystalline or coarse-grained) is shown to reduce by a few factors, while the wear resistance appears to increase by two orders of magnitude. The high strength achieved in the alloy due to the formation of the submicrocrystalline structure is maintained.
