  • Patent number: 8252430
    Abstract: A heat-resistant member is provided that includes a Ni-base superalloy substrate coated with at least one substance. The substrate and the substance are formed of materials that are substantially in a state of thermodynamic equilibrium, or in a state similar to a state of thermodynamic equilibrium, so that interdiffusion is suppressed. The heat-resistant member therefore inhibits interdiffusion of elements at the substrate/coating interface even at elevated temperatures of 1,100° C. and higher.
