Date Oct. 10, 1985.Production of high temperature materials with coatings being resistant to high temperature corrosion by forming a dual phase structure of corrosion resistant metal alloy and metal oxides. The metal oxides function as barriers for the diffusion of alloy elements, heat diffusion and electric conductivity. The result can be further enhanced by hot isostatic pressing of the coating and the use of tantalum as barrier layer, where the functioning of tantalum is the result of the low diffusion speed of tantalum in nickel base alloys. |
