THERMAL SPRAY MATERIAL AND METHOD FOR FORMING A SPRAYED COATING

WIPO Patent Application WO/2011/096233

A1

Provided is a technique that can form a dense, high-grade metal-oxide coating that is highly abrasion-resistant, corrosion-resistant, and the like, without requiring a special thermal spray device or method. The thermal spray material used is characterized by containing at least one non-vaporizing metal chelate. Said thermal spray material is heated in a thermic fluid, removing organic components from the metal chelate(s) by thermal decomposition, and the metallic components from said metal chelate(s) are oxidized, thereby generating metal oxides. Said metal oxides are carried by the thermic fluid and collide with a target object, thereby forming a sprayed coating.
