HEAT RESISTANT ALLOY MATERIAL WITH EXCELLENT HIGH- TEMPERATURE CORROSION RESISTANCE, AND ITS MANUFACTURING METHOD

Japanese Patent JP3810330

B2

PROBLEM TO BE SOLVED: To provide a heat-resistant material whose durability is improved by a film having excellent high-temperature corrosion resistance, and also to provide its manufacturing method.
SOLUTION: The heat resistant alloy material with excellent high-temperature corrosion resistance has a film which is formed by subjecting a base material composed of heat resistant alloy to diffusion coating with a metal selected from the group consisting of Al, Cr and Si and has a double-layer structure consisting of an inner layer and an outer layer; and the inner layer in which the concentration of the metallic element selected from the group consisting of Al, Cr and Si is higher than that of the outer layer is formed by the diffusion coating. The film having the double-layer structure is formed by means of an up-hill diffusion phenomenon.

JP2002519511	INDUSTRIAL APPLICABILITY: A method for forming a corrosion-resistant coating on an alloy surface.
