Title:
METHOD FOR PRODUCING TURBINE VANE
Document Type and Number:
WIPO Patent Application WO/2018/066392
Kind Code:
A1
Abstract:
This method for producing turbine vane comprises: a step for forming, on the surface of the substrate of a turbine vane formed using a Ni alloy material, an undercoat using a metal material having a higher oxidation resistance than the substrate; a step for diffusing part of the undercoat to the substrate side by heating the substrate having the undercoat formed thereupon; and a step for, after the diffusion step has been carried out, forming a top coat using a material having a lower thermal conductivity than the substrate and the undercoat, on the surface of the undercoat.
