Abstract
PURPOSE: To produce a clad material, which surface has oxidation resistance, by forming a metallic film on a surface of a substrate by mounting metallic powder grain with lower m.p. than the surface of the substrate of metal with high m.p. to said surface and by melting the surface by irradiating laser in a non-oxidation at mosphere.
CONSTITUTION: Metallic powder grain 2 of Ni, Al, Si, Cu, Pt, etc. with lower m.p. than W, Mo or these alloys is spread on an upper surface of a substrate 1 in metal with high m.p. consisting of W, Mo or these alloys in approx. unifrom thickness. The substrate is received in a box in a non-oxidation stmosphere, laser is irradiated to the metallic powder grain 2 from a laser oscillator 3, the substrate 1 is scanned, and the metallic powder grain 2 is successively disolved. Consequently, melted meatal uniformly spreads on the surface of the substrate 1 and is solidified, thus obtaining a clad material 6 in metal with high m.p., to which a metallic film 5 is compounded. This method can improve adhesion between substrates in metal with high m.p., such as, a bulb material, a disc for a rectifying element, etc. and other metallic materials and the oxidation resistance of the substrates
