Powder Selection Scheme for Laser Deposition of High Entropy Alio

摘要

According to the published literature,there are three types of laser-clad over-enriched alloy formulations on the surface of aluminum alloys,AlCrFeCoNi,AlCrMnFeCoSi,AlMnFeZnSi.AlCrFeCoNi coating was prepared on the surface of aluminum alloy by the University of Texas in the United States in 2015.It is pointed out in the paper that this component is the best quality formula among many high-entropy alloys.The process experiment is characterized by water-soluble organic The suspension was made into a suspension and then spread on the surface of the aluminum alloy using an air-spart technique and cladding with a YAG laser.This paper mainly studies the powder experimental scheme of noble alloy layer on aluminum alloy surface.
