In　order　to　solve　the　problem　of　uneven　wear　of　TC　bearing　that　conventional　method　brought　and　improve　its　service　life,　wear-resistant　coating　was　fabricated　on　the　surface　of　steel　parts　matrix　with　the　method　of　laser　additive　manufacture.　The　Cr3C2/Fe　based　alloy　was　deposited　by　laser　cladding　technique　on　the　inner-sleeve　cylindrical　and　outer-sleeve　bore　of　TC　bearing　with　two　different　process　parameters.　The　high-performance　coating　was　obtained　respectively,　of　cracks　free,　no　pores　and　with　good　metallurgical　quality.　The　morphology　of　the　laser　cladding　coating　was　observed　by　scanning　electronic　microscope　(SEM),　the　composition　was　analyzed　by　EDS,　the　phase　transformation　was　characterized　by　XRD.　The　wear　resistance,　corrosion　resistance　and　hardness　of　the　laser　cladding　layer　were　tested　by　friction　and　wear　tester,　salt　spray　test　chamber　and　digital　micro-hardness　tester　respectively.　The　results　show　that　the　average　micro-hardness　of　composite　coating　is　HV700.　The　wear　resistance　of　the　composite　coating　is　about　3　times　as　much　as　the　Ni-based　alloy.　The　corrosion　resistance　is　close　to　316L　stainless　steel.　©　2016,　Journal　of　Materials　Engineering.　All　right　reserved.
