PURPOSE:To form a diffusion structure between a parent metal and abrasion resistance metallic carbide and to make a junction strongly by charging the metallic carbide into a mold, and pouring and solidifying molten alloy. CONSTITUTION:The tungsten carbide powder is charged into the mold 1 and tampped lightly into layer, and after pre-sintering by heating in an electric furnace, molten stainless steel is poured n the sintered material. After cooling this till the room temp., it is taken out from the mold. An eutectic structure of the parent metal plug WC between the parent metal, which the molten metal solidifies, and the sintered layer of tungsten carbide, exists, and in succession, the diffusion structural layer of the parent metal into the WC sintered material and in the outer side, the WC sintered material having high hardness layer exist, and the parent metal and the WC sintered material make strongly junction by the intermediate layer.
