PURPOSE: To improve the high temp. strength and wear resistance of a member by forming the metal plated layer dispersing particles between adjoining metal substrates and joining with diffusion the space between the metal substrate and metal plated layer.
CONSTITUTION: The metal plated layer 2 subjecting the particle 3 of a ceramic particle, etc. to a dispersion eutectoid is formed by metal plating of an electric Ni plating, etc. on both faces of the metal substrate 1 of an iron foil, etc. This particle dispersion plate is pressed and heated in a vacuum or inert gas, etc. after overlapping it in plural sheets to cause the diffusion reaction of the plated layer 2 each other. In this way, the laminated plate provided with a metal substrate 1, plated layer 2 and diffused joining boundary is formed. The fine particle of a ceramic particle, etc. is uniformly dispersed in the metal and a particle disperse metal plate is laminated, so the high temp. strength, wear resistance, corrosion resistance, etc. of the member are improved.
