Abstract of the Disclosure A class of protected coatings for superalloys is described in which the coatings compositions are based on the compositions of the underlying substrate. By tailoring the coatings to the substrate composition, diffusional stability results and the other mechanical properties of the coating such as coefficient of thermal expansion and modulus, are similar to that of the substrate. Minor modifications are made to the coating in order to improve the oxidation resistance thereof.
