WIPO Patent Application WO/2016/129588
Kind Code:
A1
Abstract:
Provided is a coated member which is provided with a heat shielding coating layer that exhibits excellent characteristics in a high temperature environment in which water vapor is present. A coated member (100) which is provided with a heat shielding coating layer (102) that is composed of a zirconia-dispersed silicate wherein ZrO2 stabilized by Yb2O3 is precipitated as dispersed phases in a matrix that is a rare earth disilicate, a rare earth monosilicate or a mixed phase of a rare earth disilicate and a rare earth monosilicate. The rare earth disilicate is a (Y1-a[Ln1]a)2Si2O7 solid solution (wherein Ln1 is Sc, Yb or Lu) or a (Y1-c[Ln2]c)2Si2O7 solid solution (wherein Ln2 is Nd, Sm, Eu or Gd); and the rare earth monosilicate is Y2SiO5, [Ln1']2SiO5, a (Y1-b[Ln1']b)2SiO5 solid solution (wherein Ln1'is Sc, Yb or Lu) or a (Y1-d[Ln2']d)2SiO5 solid solution (wherein Ln2' is Nd, Sm, Eu or Gd).
