Coated member, coating material, and method of manufacturing coated member
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 (Y1-a[Ln1]a)2Si2O7 solid solution wherein Ln1 is any one of Sc, Yb, and Lu, or a (Y1-c[Ln2]c)2Si2O7 solid solution wherein Ln2 is any one of Nd, Sm, Eu, and Gd. The rare earth monosilicate is Y2SiO5, [Ln1′]2SiO5, a (Y1-b[Ln1′]b)2SiO5 solid solution wherein Ln1′ is any one of Sc, Yb, and Lu, or a (Y1-d[Ln2′]d)2SiO5 solid solution wherein Ln2′ is any one of Nd, Sm, Eu, and Gd.
