ReCr ALLOY COATING FOR DIFFUSION BARRIER |
摘要 |
Disclosed is a ReCr alloy coating for diffusion barrier formed on a substrate, such as a high-temperature equipment member, which comprises an atomic composition of 50 % to less than 90 % Re, with the remainder consisting essentially of Cr except for inevitable impurities. Even if the alloy coating for diffusion barrier includes a diffusion layer containing at least one of the group consisting of Al, Si and Cr, a desired alloy composition of the alloy coating for diffusion barrier can be assured by a surface coating process and diffused components from the substrate while substantially preventing the diffusion of the elements of the diffusion layer during a homogenizing heat treatment. The alloy coating for diffusion barrier may include a Re-containing-alloy stress relief layer inserted between the film and the substrate. The ReCr-Ni alloy coating can suppress the deterioration of the substrate and the coating layer due to the reaction therebetween to provide an extended life span of the equipment member. <IMAGE> |
