Method for forming fluoride spray coating and fluoride spray coating covered member
Abstract:
[Problem] To provide a fluoride spray coating covered member adhered with a fluoride spray coating having excellent properties on quality by suppressing a thermal decomposition reaction and an oxide reaction, and to propose a method for forming a cover by firmly adhering the coating.[Solution] A method for forming a fluoride spray coating in an implantation structure onto a substrate surface by spraying particles of a fluoride spraying material onto a substrate surface or a pretreated substrate surface, if necessary through an undercoat layer or spray particle dotted parts of carbide cermet, at a flying velocity of particles of not less than 500 m/sec with an inert gas as a working gas for coating formation at an inert gas temperature of 600° C.-1300° C. as well as a fluoride spray coating covered member.
