Compound member and method for producing the same.

摘要

A compound member and a producing method thereof comprises a core (1) and a surface layer (2) formed by plasma spray deposition of powder material. At least one intermediate layer (3) is formed between the core and the surface layer. Difference in coefficient of linear thermal expansion between adjacent layers including the core and the surface layer is 3 x 10<-><6>/ DEG C and below. The thickness of the intermediate layers (3) is 1.5 mm and over.
