    To address the issue of inadequate wear resistance on the surface of 65Mn steel, a Fe60-WC composite coating was applied to 65Mn steel via laser cladding. The microstructure, phase composition, microhardness and friction and wear properties of the cladding layer were analyzed by SEM, EDS, XRD and wear tester. The results show that the maximum elastic modulus is 338.57GPa when the WC content is 30%. The microstructure of the cladding layer is mainly composed of fine equiaxed crystal, cellular crystal and columnar crystal. The strengthening phases, including WC, W2C, Fe3W3C, Fe6W6C are added in the phase of the composite coating. Meanwhile the microhardness of the cladding layer increases with the increasing of WC content. When the WC content is 40%, the average hardness is about three times of the matrix. With the increasing of WC content, the wear volume first decreases and then increases. When the WC content is 30%, the wear volume of the cladding layer is 68% of that of the Fe60 cladding layer.
