Title:
多層合金皮膜、それを有する耐熱性金属部材および多層合金皮膜の製造方法
Document Type and Number:
Japanese Patent JP5182669
Kind Code:
B2
Abstract:
Disclosed is a multilayer alloy coating film capable of maintaining heat resistance, high-temperature oxidation resistance and creep resistance for a long time even in an ultra high temperature environment. The multilayer alloy coating film comprises a barrier layer formed on a base surface, and an aluminum reservoir layer formed on the barrier layer and composed of an alloy containing Al. The barrier layer comprises an inner sacrificial barrier layer composed of an alloy containing Re, an inner stabilization layer formed on the inner sacrificial barrier layer, a diffusion barrier layer formed on the inner stabilization layer and composed of an alloy containing Re, an outer stabilization layer formed on the diffusion barrier layer, and an outer sacrificial barrier layer formed on the outer stabilization layer and composed of an alloy containing Re.
