Purpose

The Project will investigate high temperature performance for oxidation, corrosion and wear of cold sprayed and warm sprayed high-entropy alloy (HEA) coatings and benchmark these with respect to existing high temperature resistant MCrAlY alloys used as traditional bond coat materials and/or wear resistant coatings. These traditional coatings include tungsten or chromium carbide-based cermets. The novel HEA coatings proposed in this Project may become alternatives to the traditional high temperature resistant metallic alloys and cermet overlay coatings and thus be used on a component surface that works in elevated temperature environments providing increased protection against oxidation, corrosion and wear while increasing the lifetime of the component over a wide range of operating conditions and eliminating costs associated with repair and overhaul.
