Title:
耐環境コーティング部材
Document Type and Number:
Japanese Patent JP6696802
Kind Code:
B2
Abstract:
An environmental resistant coating member 100 includes a SiC long fiber-reinforced ceramics substrate 1 and an environmental barrier coating layer 2 provided on the whole surface of the SiC long fiber-reinforced ceramics substrate 1. The environmental barrier coating layer 2 includes a SiAlON bonding layer 21 laminated on the SiC long fiber-reinforced ceramics substrate 1, a mullite layer 22 laminated on the SiAlON bonding layer 21, a reaction inhibition layer 23 laminated on the mullite layer 22, and a gradient layer 24 formed on the reaction inhibition layer 23 and having a composition that gradually changes from a rare-earth disilicate to a rare-earth monosilicate. The reaction inhibition layer 23 includes at least one of an alumina layer, a garnet layer, and a rare-earth (mono)silicate layer. When the reaction inhibition layer 23 includes two or more of these layers, the two or more layers are formed in the order of the alumina layer, the garnet layer, and the rare-earth (mono)silicate layer from a mullite layer 22 side toward a gradient layer 24 side.
