Abstract
A method and an apparatus for producing an adherent and oxidation-resistant aluminide region on the surface of a nickel- or cobalt-based superalloy article. A hypo-stoichiometric region of nickel or cobalt aluminide is produced by chemical vapor deposition on the surface of the article. Nickel or cobalt from the superalloy surface diffuses outward into the hypo-stoichiometric region, thus preventing migration of various refractory elements generally present in the superalloy, whose presence has a detrimental effect on the adhesion and oxidation resistance of a conventional aluminide region. A hyper-stoichiometric region of nickel or cobalt aluminide is then deposited by chemical vapor deposition on the hypo-stoichiometric region, to provide a sufficient supply of aluminum on the exposed surface of the article for forming a tough oxidation-resistant scale of alumina.
