COMPONENT FOR TURBINE, TURBINE, AND METHOD FOR MANUFACTURING COMPONENT FOR TURBINE

摘要

PROBLEM TO BE SOLVED: To provide a component for a turbine whose surface is restrained from deterioration.SOLUTION: A component for a turbine in an embodiment is a constituting component for a turbine. The component for a turbine in an embodiment has a component body, and an oxidation protective film provided on a surface of the component body. The component body is made of an Ni-group superalloy, a Co-group superalloy, or an Fe-group superalloy. The oxidation protective film is provided on at least one surface selected from an outer surface and an inner surface of the component body. Also, the oxidation protective film is formed by oxidizing the surface of the component body.
