ABSTRACT:
A thermal barrier coating member to be used for such as a member for a gas turbine comprising a metallic member comprising a super alloy mainly composed of at least one of Ni, Co and Fe, an intermediate layer composed of a MCrAlY alloy (M denotes at least one of Ni, Co and Fe) covering this metallic substrate, and a ceramic layer mainly composed of stabilized zirconia formed on the intermediate layer. A ceramic material having a higher melting point than zirconia is compounded in the ceramic layer as a member for suppressing a reaction sintering of the ceramic layer.
