中文摘要：
采用高能量激光束对AISI 8620合金钢表面进行冲击强化,利用CETR UMT-2摩擦磨损试验机对激光冲击试样表面进行磨损试验,并用扫描电子显微镜观察磨痕表面的形貌,研究激光冲击强化技术对AISI 8620合金钢耐磨损性能的影响。结果表明,激光冲击在AISI 8620合金钢表层形成残余压应力层,虽然残余压应力会降低氧化磨损和粘着磨损的抗性,但是会增加疲劳磨损的抗性,使AISI 8620合金钢试样的耐磨性提高1倍,多次冲击耐磨性能会更好。随着载荷的增加,激光冲击的AISI 8620合金钢试样的平均摩擦系数呈现先缓慢减小后缓慢增加的趋势。
英文摘要：
The effects of laser shock processing（LSP） on the wear behaviors of AISI 8620 steel are investigated.The dry-sliding wear tests of untreated and treated samples by LSP are conducted on a uni-directional ball-on-disk sliding wear tester（CETR UMT-2）.Wear track of AISI 8620 steel are observed by scanning electron microscope in order to investigate the wear resistant of AISI 8620 steel.Results show that LSP can induce the layer in compressive residual stress state,and the compressive residual stress will increase the resistance of fatigue wear,but it can reduce the resistance of oxidative wear and adhesion wear.As a result,LSP can double the wear resistance of AISI 8620 steel.Multiple LSP impacts can achieve better effect by comparing with a single LSP impact.The average friction coefficient decreases first and then increases with the loading force increasing during the dry sliding.
