激光冲击处理(LSP)是一种重要的表面处理方法，可以产生压缩残余应力场，改善构件的疲劳和断裂性能。本文研究了激光冲击处理对6061-T6铝合金摩擦磨损性能的影响。研究了不同工艺参数对LSP磨损率和摩擦系数的影响。滚压式摩擦试验机在不同的加载条件下使用。还对硬度和残余应力进行了评估。观察到磨损率随着脉冲密度的增加而减小，这是根据残余应力分布来解释的。
Laser shock processing (LSP) is becoming an important surface treatment to induce a compressive residual stress field, which improves fatigue and fracture properties of components. In this work, we examine the effect of laser shock processing on the wear and friction behavior of 6061-T6 aluminum alloy. Wear rate and friction coefficient evolution are investigated for different process parameters of LSP. Roll-on-flat tribometer is used with different loading conditions. Hardness and residual stresses are assessed as well. It is observed that wear rate decreases as pulse density increases; this is explained in light of residual stress distribution.
