Abstract
A heat-resistant member 10 includes a member 12 that is a target to be protected and a protective layer 14 arranged on the whole or part of a surface of the member 12. The protective layer 14 includes an oxide ceramic containing an Fe3O4 phase in which a solute component capable of forming a spinel-type oxide with Fe is solid-dissolved.
Claims12
A heat-resistant member, comprising:
- a member;
- and
- a protective layer arranged on the whole or part of a surface of the member, the protective layer including an oxide ceramic containing an Fe3O4 phase in which a solute component capable of forming a spinel-type oxide with Fe is solid-dissolved.
A method for producing a heat-resistant member, comprising a protective layer formation step of disposing a material on the whole or part of a surface of a member, the material containing an Fe metal powder and a solute component powder that contains a solute component capable of forming a spinel-type oxide with Fe, and performing firing in a temperature range lower than the melting point of an Fe oxide to form a protective layer composed of an oxide ceramic.
