THERMAL SPRAY MATERIAL AND METHOD FOR FORMING A SPRAYED COATING

WIPO Patent Application WO/2011/096231

A1

Provided is a technique for forming a high-density sprayed coating that is highly corrosion-resistant, abrasion-resistant, and the like, and is particularly resistant to corrosion by molten metals. The thermal spray material used is characterized by containing: a ceramic, a cermet, and/or a metal; and 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, along with the aforementioned ceramic, cermet, and/or metal, and collide with a target object, thereby forming a sprayed coating.
