    摘要： A high temperature sliding element is provided with a metallic film formed of any one of metals Ni, Mn, Cr, Fe and Co, and alloys of these metals on a sliding surface of a substrate of carbide ceramics or nitride ceramics in accordance with physical vapor deposition. When the substrate and a sliding counterpart ceramic member are slid in a high temperature atmosphere 500.degree. C. or higher with the metallic film intervening therebetween, wear due to sliding motion between the substrate and the counterpart ceramic member can effectively be reduced. The metallic film forms an oxidized sliding surface layer at the high temperature.
