摘要：

Fe-Cr-C　abrasive　wear　resistant　layers　were　prepared　on　Q235　steel　by　submerged　arc　welding.　The　abrasive　wear　resistance　of　the　layers　was　evaluated　by　an　MLS-225　grain-abrasion　test　machine.　The　abrasive　wear　mechanism　was　studied　according　to　the　analysis　on　of　surface　topography　by　the　micro　examination　and　energy　spectrum　analysis.　The　results　indicated　the　wear　mechanism　of　Fe-Cr-C　abrasive　wear　resistant　layer　was　mainly　attributed　to　the　exfoliation　caused　by　micro　crack.　The　desquamation　was　closely　correlated　with　the　carbide.　Energy　spectrum　analysis　indicated　that　the　Cr　content　in　the　crater-like　pits　was　inosculated　with　the　Cr　content　in　(Cr,　Fe)7C3,　which　proved　that　carbide　rupture　caused　crater-like　pits.
