METHOD FOR FORMING FLUORIDE SPRAY COATING, AND FLUORIDE SPRAY COATING COVERED MEMBER

摘要

[Problem] To provide a fluoride spray coating covered member in which a fluoride spray coating firmly adheres by coating carbide cermet to a surface of a substrate and interposing it, and to propose a method therefor. [Solution] A fluoride spray coating is formed in such a manner that an undercoat layer of carbide cermet, which covers a substrate in a film-shaped manner while a tip portion of carbide cermet particles is embedded in the substrate, or a primer part of carbide cermet, is formed by blowing a carbide cermet material at a high velocity by using a spray gun to a surface of the substrate, and after that, a fluoride particle is sprayed thereon.

1. A method for forming a fluoride spray coating characterized in that an undercoat layer of carbide cermet, which covers a substrate in a film-shaped manner while a tip portion of carbide cermet particles is embedded in the substrate, or a non-film shaped primer part of carbide cermet, is formed by blowing a carbide cermet material by using a spray gun for a high velocity spraying to the roughened substrate surface and after that, a fluoride spray material is sprayed onto the undercoat layer or the primer part.
