Abstract:
A thermal barrier-coated Ni alloy component (10) includes: a substrate (12) made of a Ni alloy containing Al; an intermediate layer (14) formed on a surface of the substrate (12); and a thermal barrier layer (16) made of a ceramic and formed on a surface of the intermediate layer (14). The intermediate layer (14) includes a ³' layer (18), which is formed from a ³'-Ni 3 Al phase on the surface on the thermal barrier layer (16) side, and contains Pt.
Abstract:
An Ni alloy article (10) coated with a thermal shield, said article including a base material (12) formed from an Al-containing Ni alloy, an intermediate layer (14) formed on a surface of the base material (12), and a thermal shield layer (16) that is formed from ceramic and on a surface of the intermediate layer (14). The intermediate layer (14) includes, on a surface on the side of the thermal shield layer (16), a Pt-containing ?´layer (18) that is formed from a ?´-Ni3Al phase.
