Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a wear-resistant surface treatment process that can stand high-temperature fluid generated through combustion at a temperature further higher than that in conventional high alloy coating films. SOLUTION: In the wear-resistant surface treatment process for a high- temperature member, the member is formed by embedding a body material 4 in a mixed power 3 comprising metal powders, a heat-resistant film-forming agent powder, or the like., and heating the material 4 at an elevated temperature. Here, metal aluminum powder and a metal silicon powder are used as the metal powders, an alumina powder is used as the heat-resistant film-forming powder, and ammonium chloride is used as a reaction accelerator. Heating is conducted at an elevated temperature of 800-1,000 deg.C while circulating argon gas within the mixed powder.
