Effects of WC-Ni content on microstructure and wear resistance of laser cladding Ni-based alloys coating

► Different WC-Ni contents of NiCrBSi/WC-Ni composite coatings were produced by laser cladding. ► The effect of WC-Ni added on the microstructure, composition and microhardness was analyzed. ► The tribological properties of the Ni-based alloy coatings were investigated.
