The influence of nanostructural oxide films on wear-resistance of titanium materials

Abstract

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.
