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.

Abstract: A heat resistant member includes a metal or ceramic substrate and a thermal-barrier coating layer disposed on the substrate. The thermal-barrier coating layer includes a metal layer functioning as a bonding layer and one or more ceramic layers disposed on the metal layer. At least one of the ceramic layers is mainly composed of a hafnium oxide-based ceramic layer containing 85% or more of hafnium oxide. Due to the above structure, there can be provided a heat resistant member with high heat resistance and durability which has a thermal-barrier coating layer with stable thermal conductivity at elevated temperatures, namely, not less than 1,200° C., and resistance to cracking and delamination due to sintering.

Abstract: A high temperature component such a gas turbine high temperature component, for example, constituting movable or stationary blade portion, thereby comprises a base material and a thermal barrier coating coated on a surface of the base material. The thermal barrier coating has a thermal barrier characteristic controlled in accordance with an environment to which a high temperature component is exposed so as to make substantially uniform a surface temperature of the base material. The thermal barrier coating comprises a thermal barrier ceramic layer having a thermal barrier characteristic capable of being controlled by varying a thickness thereof at portions of the thermal barrier ceramic layer.
