High heat - and oxidation-resistant coating and high heat - and of oxidation-resistant, multi-layer material

摘要

PROBLEM TO BE SOLVED: To provide a high heat resistant and oxidation resistant coating film provided with a self-repairing function of personally decreasing crack under an aerodynamic heating environment and having low catalytic property, and a high heat resistant oxidation resistant laminated body.;SOLUTION: In the self-repairing high heat resistant and oxidation resistant coating film containing silicate, the silicate consists essentially of a multiple oxide of a lanthanoid based rare earth element containing yttrium and silicon and the self-repairing high heat resistant and oxidation resistant coating film and the self-repairing high heat resistant and oxidation resistant laminated body are obtained by dispersing the silicate in particles in a vitreous matrix.;COPYRIGHT: (C)2002,JPO
