Zusammenfassung:	PURPOSE:To give excellent wear resistance and seizure resistance by sticking powdery aggregate or powdery forming body composing or carbide of the specific kind and quantity and the specific metallic phase, to surface of metallic member and then integrating them by fusing. CONSTITUTION:The powdery aggregate or powdery forming body is composed of 20-80mol% total of one kind or more of carbides of V, Ti, Zr, Nb, Ta, Hf and the remaining part of one kind or more of metals or alloy of Fe, Ni, Co or one kind or more of alloy as main component of Fe, Ni, Co and inevitable compounds. After sticking this powdery aggregate or powdery forming body to the surface of metallic member, the powdery aggregate or powdery forming body is fused by heat source having high energy density, to integrate the powdery aggregate or powdery forming body with the surface of metallic member by fusing.
