PURPOSE: To obtain a clearance adjusting film layer having good productivity at a low cost, by forming the bed layer of silicone system resin after applying short-blast on a housing, and forming the film layer of a silicone system resin including ceramic balloons and ceramic fibers.
CONSTITUTION: Shot blast is applied on a part 6 opposing to the impeller of a compressor housing 5, and then degreasing cleaning and drying are applied thereon. After bed paint made of silicone system resin including color pigment and corrosion preventing pigment is applied thereon, it is dried so as to form a bed layer 7d. Film paint made of silicone system resin including ceramic balloons 7a and ceramic fibers 7b is applied on the bed layer 7d, and after that, it is dried so as to form a film layer 7f. In the clearance adjusting film layer 7f, since cutting resistance by an impeller is smaller in comparison with that of the layer formed by a flame sprayed material, and the layer 7f is formed by brush painting or spray painting, it is thus possible to form the film layer if a low cost, improve its productivity, and reduce unevenness of the film.
