Imparting high-temperature degradation resistance to components for internal combustion engine systems

Are the method of giving high temperature-proof degradation nature to the parts relevant to an internal combustion engine, and the thing; for which the metal slurry containing Co fund group ingredient, a binder, and a solvent is applied to the surface of the above-mentioned parts, and the above-mentioned Co fund group ingredient are sintered, It is a method including forming continuous Co base alloy covering on the surface of a main part substantially. It is a metal base material and internal combustion engine parts including Co base alloy covering on it, and Co base alloy covering is internal combustion engine parts which have the thickness of 1000 microns of abbreviation 100* abbreviation.
