Abstract：

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.
