摘要： PURPOSE: To form thermal spraying films having high intergranular strength without having pores in these films by forming a specific amt. of the films on a substrate heated to its m.p. or below, then forming the films of a specific thickness by plasma spraying while heating the film surface to the b.p. of the films or below. CONSTITUTION: The substrate (low-carbon steel, etc.) is heated to a temp. range of 100 to the m.p. of the substrate or below prior to thermal spraying and the film (Ni-base alloy, etc.) of a thickness of 0.1 to lmm is formed on the substrate. While the film surface is heated to a temp. range from the m.p. of the film up to the b.p. or below by a high frequency plasma, the molten layer is subjected to thermal spraying, by which the films are formed to a thickness of 2 to 20mm. As a result, the thick thermal spraying films which have no reaction layers at the boundary of the base material and the films, are dense, have high strength and have excellent wear resistance are formed.
