A　Fe-based　composite　coating　reinforced　by　in　situ　synthesized　TiB2　and　TIC　particles　was　fabricated　on　Cr12MoV　steel　by　using　6KW　fiber　laser　cladding.　The　microstructure　and　the　microhardness　of　the　coating　in　profile　across　were　investigated　by　means　of　X-ray　diffraction,　scanning　electron　microscopy　(SEM),　energy　dispersive　spectroscopy　(EDS),　transmission　electron　microscope　(TEM)　and　a　hardness　tester.　The　abrasive　wear　resistance　of　coating　was　evaluated　using　a　MLS-225　wet　sand　rubber　wheel　testing　machine.　The　coating　mainly　consists　of　TiB2,　＇TIC,　Fe2B　and　alpha-Fe.　The　grains　are　refined.　There　are　no　cracks　and　few　stomas　in　the　coating.　Defect-free　coating　with　metallurgical　joint　to　the　substrate　was　obtained.　From　the　surface　of　cladding　layer　0.8　mm　the　highest　micro-hardness　is　up　to　HV920,　obviously　higher　than　that　of　the　substrate.　Due　to　the　exhibits　of　TiB2　and　TIC　phases,　the　laser　clad　coating　has　good　wear　resistance.
