摘要：

Fe-Cr-C-Ti　hardfacing　alloys　with　different　Ti　contents　were　prepared　by　gas-shielded　flux　cored　arc　welding　on　Q235　steel.　The　microstructures　were　investigated　by　SEM,　XRD　and　EPMA.　The　abrasive　wear　resistance　performance　of　the　welded　surfacing　layers　was　evaluated　on　the　MLS-225　grain-abrasion　testing　machine.　The　abrasive　wear　mechanics　was　studied　on　the　observation　of　surface　topography　by　the　micro　examination　and　energy　spectrum　analysis.　It　is　indicated　that　with　the　increasing　of　Ti　content,　the　content　of　TiC　increases.　The　carbides　distribute　more　symmetrical,　but　significantly　decrease　when　Ti　content　is　up　to　7.5%.　The　results　show　that　the　alloy　with　5.5　%Ti　has　better　wear　resistance.
