COATING COMPOSITION FOR SLIDING MEMBER, AND SLIDING MEMBER
Provided is a coating composition for a sliding member, the coating composition being used for forming a coating on the surface of a sliding member. The coating composition contains a binder resin, a solid lubricant, and a wear-suppressing material.

A heat insulating film (10) formed on at least a portion of the surface of a component 2 to be heat-insulated is formed from: an inorganic compound layer 20 in which scaly inorganic particles 22 are dispersed in an inorganic compound 21 formed from an alkoxide; and a top coat 30 that is formed on the inorganic compound layer 20, has a thickness of 0.5-30 µm, and is formed by an organic-inorganic hybrid material comprising a mixture of a metal alkoxide and a resin. By the formation of the top coat 30, voids 23 or microcracks in the inorganic compound layer 20 are filled by the organic/inorganic hybrid material, and the surface of the inorganic compound layer 20 is covered, whereby the heat insulating performance of the heat insulating film 10 is enhanced, and fuel efficiency of an engine is improved by forming the heat insulating film 10 on piston top surfaces of the engine.
