Abstract:high entropy alloy (HEA) SiFeCoCrTi coating is prepared on Q235 steel by laser cladding. effect of WC Particles on the Microstructure and Properties of High Entropy Alloy SiFeCoCrTi coating is researched.in this paper, the organization,phase, microhardness and wear resistance are investigated by means of OM，XRD，SEM, hardness testing and wear testing. the experimental result shows that he microstructure of the HEA SiFeCoCrTi coating is dendrite consisting of BCC phase and intermetallics. the coating form grain dendrite after adding WC particle, and large amounts of intermetallics are found in the coating, such as TiCo3、Co1.07Fe18.93. the substrate’s dilution rate decrease and the properties of coating increase with adding WC particle. comparing to the HEA FeSiCrCoMo coating, the average hardness of the HEA FeSiCrCoMo coating increased by 23% and both of wear rate and friction coefficient decreased with adding WC, the wear-resisting property is improved obviously.
