| Abstract: | The coatings of the (TiCrC)-(FeCr) composite are deposited on steel and titanium alloy by plasma method. The composition,
structure, and tribotechnical properties of these coatings are studied in comparison with traditional materials based on the
Ni-Cr alloy. The effect of preliminary surface treatment methods, i.e., sandblasting treatment and electrospark alloying,
on coating properties is examined. The fretting corrosion of coatings is investigated. It is established that coatings based
on double titanium-chromium carbide have considerably greater wear resistance than that of Ni-Cr alloys at almost equal friction
coefficients. It is established that electrospark alloying is competitive with traditional sandblasting treatment in environmental
effect and coating-to-based adhesion.
