A number of aluminide coatings have been developed which are modified by additional elements (noble metals, Cr and reactive elements such as Y and Hf). This results in a marked improvement in their corrosion resistance. In the present paper, aluminide coatings are reviewed. The hot corrosion and oxidation resistance of these coatings in laboratory and field tests under different conditions are studied.
