The wearing mechanism of titanium material of the Тi-Cr-TiC composition obtained by different ways of leading chromium and carbon into titanium as separate elements Cr and TiC or as a compound Cr3C2 was investigated. The formation of nanostructural oxide films acting like a solid lubrication at friction on the surface of titanium materials was shown. Defensive properties of the oxide films on the friction surface of Тi-Cr3C2 material are stronger. The structure of such a material consists of small titanium carbide engagings that have a strong connection to titanium-chromium base and work till the abrasion.
