文摘

FeCoCrAlNiTix coatings were prepared on 304 substrate by laser surface alloying. The formation rules of solid solutions in high-entropy alloy were investigated. The microhardness of the coating was at least 3.6 times that of 304 substrate. The mechanism of erosion-corrosion for HEA coatings were investigated.
