Abstract:
A spray coated member for use at a high temperature, having a composite sprayed coating comprised of an oxide-containing undercoat sprayed coating obtained by spraying a MCrAlX alloy spraying material (wherein M is one or more of Ni, Co and Fe, and X is one or more of Y, Hf, Ta, Cs, Pt, Ce, Zr, La, Si and Th) onto a surface of a heat-resistant alloy substrate in air and a non-oxide topcoat sprayed coating obtained by spraying a MCrAlX alloy spraying material (wherein M is one or more of Ni, Co and Fe, and X is one or more of Y, Hf, Ta, Cs, Pt, Ce, Zr, La, Si and Th) onto the undercoat under a low pressure containing substantially no oxygen.
