Atmospheric plasma spraying, high-velocity oxy-fuel spraying and warm spraying processes were used to prepare NiCo0.6Fe0.2Cr1.5SiAlTi0.2 and NiCo0.6Fe0.2Cr1.3SiAl high-entropy alloy coatings for the investigation of their high temperature properties. The best-performer, the warm-sprayed high-entropy alloy coating was then applied to a thermal barrier coating system as a bond coat over an Incoloy 800H substrate. Experimental results show that the investigated high-entropy alloy coatings have high hardness, excellent wear resistance and good oxidation resistance at 1100C that makes them promising overlay coatings for elevated temperature applications.
