Abstract

1457033 Coated superalloys GENERAL ELECTRIC CO 11 Jan 1974 [23 April 1973] 01318/74 Heading C7F A Ni or Co-base superalloy is coated with an alloy of Cr, Al, at least one of Fe, Co and Ni, and optionally Y, or a rare earth element, followed by a coating of Al, both coatings applied by vapour deposition, after which the coated substrates are heated to melt the Al and allow it to diffuse into the first layer. The first coating preferably consists of 14-35% Cr, 4-20% Al, 0-3% Y, the balance being Fe, Ni, Co, or a mixture thereof. In examples the first coating may be of Co 64%, Cr22%, Al 13%, Y 1%; Ni 65%, Cr 20% Al 15%; and Fe 64%, Cr 25%, Al 10%, Y 1%. The first coating is preferably 1-7 mil thick, and the Al coating is preferably 0.1-3 mil. The heating takes place above 950‹C.
