PROBLEM TO BE SOLVED: To provide a wear resistant thermal spray coating which has improved wear resistance, seizure resistance, initial fitness or the like in the sliding part, and can be applied to the inside face of the cylinder bore of an engine. SOLUTION: The thermal spray coating has a poly-phase mixed structure where a soft phase (graphite) is dispersed into an Al-Si-based alloy, or a hard phase (chromium oxide or chromium carbide) and a soft phase (graphite) are simultaneously dispersed therein. In the method of producing the coating, an atmospheric plasma spraying method is used. COPYRIGHT: (C)2004,JPO&NCIPI
