In　this　paper,　the　enhancement　of　NiCrBSi　coatings　by　adding　Cr3C2　were　investigated.　The　NiCrBSi　coatings　with　different　additions　of　Cr3C2　were　produced　by　laser　cladding.　The　microstructure,　hardness　and　wear　resistance　of　the　coatings　were　studied　by　optical　microscope　(OM),　scanning　electron　microscopy　(SEM),　X-ray　diffraction　(XRD),　microhardness　tester　and　M-200　wear　tester.　It　is　found　that　the　main　phases　in　the　coatings　are　gamma-Ni,　Cr23C6　and　Cr7C3,　and　they　also　contain　a　small　amount　of　CrB,　Ni4B3　and　Ni3Si2.　Moreover,　with　the　increase　of　Cr3C2　addition,　the　microhardness　and　wear　resistance　of　coatings　are　obviously　improved.　When　the　addition　of　Cr3C2　is　20%,　the　wear　resistance　of　the　coating　is　the　best,　and　the　wear　resistance　of　the　coating　increased　by　191.2%　than　that　of　the　Cr3C2-free　coating.　The　wear　resistance　of　coating　decreases　when　the　addition　of　Cr3C2　reaches　30%.
