Abstract
PURPOSE:To bind dispersion material films and the base material metal of a molding firmly by carrying out metallic plating to a metallic substrate of a porous base material then subjecting the same to a gaseous treatment then to compaction working and sintering. CONSTITUTION:First, metallic powder of a base material is compression molded to a porous molding 1 to have about <=70% density. Then, metal 3 which is a base material for dispersion material is plated on the molding 1 to coat the surfaces and fine pores 2 of the molding 1 with the metal 3. Next, a treating gas is passed through the inside of the molding 1 to perform an oxidation, a nitration or a carbonization treatment properly, whereby the dispersion material films 4 oxidizing, nitriding or carbonizing the metal 3 are obtained. This is compression molded preferably by hydrostatic pressure to prescribed density in the state in which the pores 2 annihilate and the materials 4 disperse linearly in the molding 1. Further in order to improve the strength after the compression molding, the molding is sintered to a desired sintered body 5.
