ABSTRACT:
A high temperature oxidation and corrosion resistant coated nickel-base superalloy article comprising (a) a nickel-base superalloy article, and [(b) a first] adjacent thereto (b) a CoCrAl(Y) coating having a substantially uniform composition [consisting essentially] composed of, on a weight basis, approximately 26-32% chromium, 3-9% aluminum, 0-1% yttrium, the rare earth elements, platinum or rhodium, and the balance [nickel] cobalt and impurities ordinarily associated with the aforementioned constituents.
