PARTICLE FOR THERMAL SPRAYING, METHOD FOR FORMING THERMALLY SPRAYED COATING FILM, AND THERMALLY SPRAYED MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a particle for thermal spraying which provides a flat and smooth and compact thermally sprayed coating film having excellent flowability without the need of surface polishing processing.SOLUTION: A particle for thermal spraying is a particle used as a raw material for thermal spraying and is obtained by being subjected to surface treatment with at least one organosilicon compound selected from organoalkoxysilane, organohalogensilane, and organoalkoxy halogensilane, wherein an average particle diameter of the particle is 45 μm or less. The particle for thermal spraying has excellent flowability even when it is a small inorganic particle with a small particle diameter, and the surface of a coating film obtained by performing thermal spraying of the particle for thermal spraying becomes flat and smooth and compact and has excellent adhesion and corrosion resistance.
