MCrAlY coatings are generally used in the design of turbine blades and vanes to protect the thin-walled airfoil from high temperature oxidation and hot corrosion (type I and II). The chemical composition of such coatings has been optimized through decades to form adherent thin- and low-growth-rate oxides (±-Al2O3 - commonly denoted thermally grown oxide (TGO) - for high temperature oxidation protection and Cr2O3 for intermediate temperature corrosion). The addition of reactive elements strongly improved the efficiency of coatings under thermal cycling stresses, limiting the oxidation rate of the so-called TGO and thus its early spallation. The oxidation resistance of MCrAlY coatings is one of the most important factors to compare them. In this paper the oxidation resistance of new designed MCrAlY coating with advanced chemical composition include Hf and Ta was compared to two other conventional MCrAlY coatings by isothermal oxidation test. The new MCrAlY coating indicates oxidation resistance improvement between the evaluated powders and can be introduced as a new powder to industrial application.
