POWDER FOR THERMAL SPRAYING, METHOD FOR MANUFACTURING THE SAME, AND THERMAL SPRAYING METHOD USING THE POWDER FOR THERMAL SPRAYING

摘要

PROBLEM TO BE SOLVED: To provide powder for thermal spraying which can prevent thermal decomposition of molybdenum disulfide in a thermal spraying process and permits formation of a thermally sprayed film containing the molybdenum disulfide, a method for manufacturing the same, and a thermal spraying method using the powder for thermal spraying.

SOLUTION: The powder for thermal spraying consists of molybdenum disulfide particles provided with film layers consisting of metal (for example, copper) which softens or melts at the temperature lower than the thermal decomposition temperature of the molybdenum disulfide on the surfaces. The method for forming coating layers on the surfaces of the molybdenum disulfide particles is preferably an electroless plating method. Also, a high-velocity flame thermal spraying machine 11 having prescribed configuration is preferably used in thermal spraying the powder for thermal spraying.
