Research on Surface Profile of Copper Treated by Multi-Micro Laser Shock Peening
摘要
为了研究多点激光微喷丸对表面形貌的影响,采用实验方法测试了激光微喷丸处理后纯铜材料的表面形貌,对不同工艺参数条件下的处理表面进行了分析,给出了合理的表征方式,探讨了主要工艺参数对表面形貌的影响规律。结果表明,激光微喷丸后表面粗糙度增加;激光脉冲能量和搭接率是影响表面轮廓以及轮廓支承长度率的主要因素;通过对多点激光微喷丸强化纯铜表面形貌的分析和合理表征,为工艺参数的选择和表面质量的有效控制提供理论指导。
Abstract
In order to investigate the effect of multi-micro laser shock peening on surface morphology, experiments are adopted to analyze the surface profile of copper under different processing conditions. Based on the experimental and theoretical analysis, a reasonable characteristic method is presented, and influence rule of main processing parameters is also explored. The results show that surface roughness increases after laser shock peening, laser pulse energy and overlapping rate are the main influence factors on surface profile and bearing length ratio. With reasonable characterization of surface morphology, good guidance for further control of surface profile and optimal parameters of microscale laser shock peening are provided.
