Influence of Cu on microstructure and wear resistance of TiC/TiB/TiN reinforced composite coating fabricated by laser cladding

► Fe/Al + B4C/SiC laser-cladded coating can improve the surface performance of the titanium alloys. ► Cu is able to improve the microstructures and wear resistance of this coating. ► This Cu reinforced coating exhibited a compact microstructure free of the pores and micro-crack. ► With addition of Cu, TiB2 crystals have enough time to grow up. ► The grew TiB2 crystals are beneficial in improving the performance of this coating.
