Deposition of High-Entropy Alloy (HEA) coatings by HVOF and cold gas spray

Journal of Alloys and Compounds
High-entropy alloy (HEA) coatings were deposited by high-velocity oxygen fuel (HVOF) and cold gas spraying (CGS) using mechanically alloyed feedstock materials, as an alternative to conventional coatings such as Stellite. Cr-Mn-Fe-Co-Ni and Alx(Cr20Mn25Fe40Ni15)100-x (x =0, 10, 14) alloys were considered.
