摘要：

Laser　cladding　include　Ti-Fe,B4C　Fe-based　alloy　coating　was　fabricated　on　the　surface　of　Cr12MoV　automotive　mold　steel　by　using　6　kW　fiber　laser,　in-situ　synthesized　TiC+TiB2　ceramic　phase　reinforced　Fe-based　coating　on　the　surface　of　Cr12MoV　automotive　mold　steel.　The　gains　are　refined.　Phases　were　presented　in　the　coating　evolved　into　TiB2,　TiC　and　α-Fe.　Dese　and　defect-free　coating　with　metallurgical　joint　to　the　substrate　was　obtained.　Cladding　layer　1.2　mm　from　the　surface　of　the　highest　microhardness　is　up　to　1　000　HV.　©,　2015,　Harbin　Research　Institute　of　Welding.　All　right　reserved.
