摘要

A medium-entropy high-speed steel (ME-HSS) coating with the 76 at.％ of Fe and multiple alloying elements was prepared by the wide-band laser cladding.Compared with the commercial W6Mo5Cr4V2 (M2) HSS coating which contains a large number of network lamellar M2C-type carbides along the grain boundaries,the presented ME-HSS coating has a high quantity of finer and more uniformly dispersed MC-type carbides;on the other hand,the coating has less retained austenite and much lower brittleness as well as similar secondary hardening effect and tempering hardness.
