COATED MEMBER AND METHOD FOR PRODUCING COATED MEMBER
Provided are a coated member in which damage of a coating film can be suppressed in a high temperature environment and the coating may be performed at low cost, and a method of manufacturing the same. A coated member 100 includes a bond coat 102 and a top coat 103 sequentially laminated on a substrate 101 made of a Si-based ceramic or a SiC fiber-reinforced SiC matrix composite, wherein the top coat 103 includes a layer composed of a mixed phase of a (Y 1-a Ln 1a ) 2 Si 2 O 7 solid solution (here, Ln 1 is any one of Nd, Sm, Eu, and Gd) and Y 2 SiO 5 or a (Y 1-b Ln 1 ' b ) 2 SiO 5 solid solution (here, Ln 1 ' is any one of Nd, Sm, Eu, and Gd), or a mixed phase of a (Y 1-c Ln 2c ) 2 Si 2 O 7 solid solution (here, Ln 2 is any one of Sc, Yb, and Lu) and Y 2 SiO 5 or a (Y 1-d Ln 2 ' d ) 2 SiO 5 solid solution (here, Ln 2 ' is any one of Sc, Yb, and Lu).
