摘要
为了研究激光冲击强化(LSP)对铜表面质量和性能的影响,利用Nd∶YAG激光器对铜试样进行冲击强化处理。试验结果表明,以高分子黑胶带作为吸收层时,试样的表面形貌几乎没有缺陷;随着搭接率的提高,最大硬度增加,且表面粗糙度降低。两次冲击重叠和错开的冲击方式对试样影响层深度和最大硬度的影响类似。仿真结果显示,错开的冲击方式可提高试样的残余压应力。
Abstract
In order to study the effects of laser shock peening (LSP) on surface quality and property of copper, Nd∶YAG lasers is used to treat copper samples by laser shock peening. The experimental results show that, when the polymer black tape is used as the absorption layer, there are no defects on the surface morphology of sample. With the increase of the overlap rate, the maximum hardness increases and the surface roughness decreases. The effects on the affected layer depth and the maximum hardness of sample caused by the overlapped and the staggered shock ways of two shocks are similar. The simulation results show that the staggered shock way can enhance the residual compressive stress of sample.
