应用激光堆焊技术对磨损轴件的修复工艺

Research of Repairing the Abraded Shafts Using Laser Overlaying Welding Technology

采用激光堆焊技术及自动送粉工艺进行了轴件修复实验。采用为检验激光修复的性能 ,对相同条件下 (材料、工艺等 )获得的试样进行了性能测试。用金相显微镜分析了堆焊层及过渡区的金相组织 ,用HXD - 10 0

In this paper we tried to repair the abraded shafts using laser overlaying welding technology. We repaired the shaft using automatic powder-feed technology. We analyzed the metallography microstructure of welding welding-layer using metallography microscope, tested its microhardness using HXD-1000 microhardness instrument.
