Abstract
A coated member includes a heat-shielding coating layer made of a zirconia-dispersed silicate in which ytterbia-stabilized zirconia is precipitated as a dispersed phase in a matrix phase which is any one of a rare earth disilicate, a rare earth monosilicate, and a mixed phase of the rare earth disilicate and the rare earth monosilicate. The rare earth disilicate is a (Y[Ln])SiOsolid solution wherein Lnis any one of Sc, Yb, and Lu, or a (Y[Ln])SiOsolid solution wherein Lnis any one of Nd, Sm, Eu, and Gd. The rare earth monosilicate is YSiO, [Ln']SiO, a (Y[Ln′]b)SiOsolid solution wherein Ln′ is any one of Sc, Yb, and Lu, or a (Y[Ln′])SiOsolid solution wherein Ln′ is any one of Nd, Sm, Eu, and Gd.
