An article of improved oxidation resistance includes a metal base of a NiCr dispersion-modified alloy including, by weight, 15 - 30% Cr, 0.1 - 10% of oxides selected from oxides of the rare earth elements, particularly Th, Y and La, up to 1% of elements selected from Ti and Al, with the balance Ni and incidental impurities. To the base is applied a coating consisting essentially of, by weight, about 8 to less than about 14% Al, about 15 - 30% Cr, about 0.01 - 10% of elements selected from Y and Hf, with the balance essentially nickel and incidental impurities.
