A wear-resistant titanium metal member includes a substrate having a carburized layer formed by plasma carburizing and a polished surface having a surface roughness Ra of 0.01 to 0.80 μm formed on the surface of the carburized layer, a titanium oxide layer superposed on the polished surface, and an amorphous carbon (GLC) layer superposed on the titanium oxide layer. The GLC layer is rigid and has a flat and smooth surface, so that it is free of stress concentration. By adjusting the plasma carburizing temperature and the concentration of the carburizing gas, carbon ions can penetrate the polished surface and form the carburized layer under the polished surface. |
