Wear-resistant coatings were fabricated by laser cladding with direct injection of the Ni-Cr-B-Si powder. Laser cladding was conducted with a Rofin-Sinar CW025 YAG laser. Laser cladding coatings were characterized by scanning electron microscopy (SEM, LEO1450), energy disperse spectroscopy (EDS) and X-ray diffraction (XRD). The results show that there is a good metallurgical bonding between the coating and the C86300 bronze substrate without pores and cracks. The laser cladding Ni-Cr-B-Si alloy coating was mainly γ-Ni, Cr7C3, Ni2B, Ni3B together with lesser proportions of CrB2 and Cr3Si. The basic elements (Cr, Fe, Ni, Cu and Zn) content from the bronze substrate to the coatings vary regularly. Near the interface, the main elements are gradient distributed.
