In　order　to　solve　the　problems　of　low　hardness　and　poor　wear　resistance　of　titanium　alloy,　laser　cladding　technology　was　used　to　prepare　Ti(C,B)/Ni　coatings　with　different　amount　of　Cr3C2　on　the　surface　of　Ti-6Al-4V　titanium　alloy.　The　effects　of　Cr3C2　content　on　the　microstructure,　hardness　and　wear　resistance　of　Ti(C,B)/Ni　coating　were　investigated　by　methods　of　scanning　electron　microscope　(SEM),　x-ray　diffractometer　(XRD),　microhardness　tester　and　M-200　wear　tester.　The　results　showed　that　phases　existing　in　coating　mainly　contain　gamma-Ni,　Ni3Ti,　NiTi,　TiB2,　Ti(C,B)　and　CrB.　With　the　increase　of　Cr3C2　content,　the　size　and　number　of　black　bulk　precipitates　in　the　coating　reduced.　Meanwhile,　the　short　rod-like　Ti(C,B)　particles　grew　and　the　amount　of　the　particles　increased,　and　Ti(C,B)　particles　existed　in　the　form　of　cellular　dendritic　crystals　in　the　coating.　The　average　microhardness　of　the　cladding　layer　without　Cr3C2　addition　is　896.7　HV0.2,　which　is　about　1.5　times　higher　than　that　of　Ti-6Al-4V　substrate　(360　HV0.2).　With　the　increase　of　Cr3C2　content　(10,　20,　30　wt.%),　the　average　microhardness　of　the　coating　increased　to　948.7,　990.4　and　1035.8　HV0.2,　respectively.　The　average　hardness　of　the　coating　added　30　wt.%Cr3C2　is　15.5%　higher　than　that　of　the　Cr3C2-free　coating.　At　the　same　time,　the　wear　resistance　increased　with　the　increase　of　Cr3C2　content.
