Abstract
A Ni-based superalloy component includes a bond coat layer having a chemical composition not allowing interdiffusion to occur on a Ni-base superalloy substrate, and by allowing the bond coat layer to have Pt and/or Ir content equal to or higher than 0.2% but not exceeding 15% by mass, generation of an SRZ, which occurs at an interface between the Ni-base superalloy substrate and the bond coat layer in a high-temperature oxidizing atmosphere, can be suppressed, and at the same time adhesion at the interface between a ceramic thermal barrier coat layer and the bond coat layer is improved. Thus, a long-life Ni-based superalloy component with suppressed elemental interdiffusion between the Ni-base superalloy substrate and the bond coat layer even at temperatures exceeding 1100° C. is provided.
