The laser cladding Cr3C2/Ni coating was prepared under the optimized process parameters, and the Cr3C2/Ni cladding layer was remelted with the same process parameters. The effects of remelting on the microstructure and properties of single pass and multi pass Cr3C2/Ni cladding layer were studied. The results show that the average hardness of Cr3C2/Ni single pass cladding layer decreases from 893.26 HV to 748.33 HV, which decreased by 16.23%, and columnar crystals with obvious growth direction appear in the middle of the single pass cladding layer. The average hardness of Cr3C2/Ni multi-pass cladding layer decreases from 844.75 HV to 819.92 HV by 2.93%. After remelting, the microstructure of multi-pass cladding layer is more uniform and fine, the wear resistance of cladding layer relative to GCr15 steel is reduced from 0.68 to 0.45, the adhesive wear is intensified, the bending strength of remelting cladding layer is improved and the plasticity is enhanced. While remelting improves the surface forming quality of Cr3C2/Ni multi-pass cladding layer, the microhardness remains high, the wear resistance decreases slightly, and the bending strength increases.
