摘要
用机器人光纤激光系统, 在45#钢表面作Fe316L铁基粉末激光单道和多道的同轴同步送粉熔覆, 以提高材料表面的硬度及耐磨性能。用金相显微镜对熔覆层剖面分析测量, 用维式硬度计对基材和熔覆层显微硬度测量结果表明: 用光纤激光同轴同步的复合送粉嘴做单道激光熔覆时, 选700~950 W的激光功率及60%的搭接率, 能获得合适的稀释率(35%~55%)和熔覆层厚度(1.25~1.70 mm); 有效的消除了搭接处微裂纹和气孔等组织缺陷; 试样熔覆层显微硬度显著高于基材硬度, 达二倍以上。
Abstract
The single-or multiple-trace synchronous coaxial powder feeding cladding of Fe316L iron-based powder over 45 steel surface is performed by robotic fiber laser in order to improve the hardness and wear resistance The cladding layer profiles are measured and analysted with a metallografic instrument, the micro-hardness of the cladding layer and substrate measured by a Vickers hardness instrument .The results showed that perfect cladding layer thickness with appropriate r dilution rate is able to be gotten in operation of single trace laser scan, if using fiber laser synchronous coaxial powder feeding nozzle, and selecting 700~950 W of laser power and 60% of overlapping ratio.The micro-cracks, holes and other organization defects in overlapping position can be effectively eliminated ,and the micro-hardness of cladding layer on the specimens is significantly higher than the substrates, reaching more than twice.
