ABSTRACT:
A mixture of ceramic particles (such as SiC particles) with metallic powder (such as iron-base particles, e.g., stainless steel particles) is placed in a predetermined position of an internal wall of a mold and a molten metal (e.g., molten iron-base metal, particularly molten cast iron) is poured into the mold. In this manner a wear-resistant layer is formed in a necessary portion on a surface of the casting at the same time when casting is conducted.
