摘　　要：研究激光喷丸的机理及涂层和约束层的应用技术。针对LY2航空铝合金材料,进行试件激光喷丸实验,通过对激光喷丸前后材料性能的测试,分析激光喷丸对提高航空铝合金材料抗疲劳、抗打伤性能的影响,并分析原因。The mechanism of laser shock peening and application of the coating and limiting layer are studied. The laser shock peening experiment of LY2 aerial aluminum alloy is carried out and its capability is tested. The influence on the fatigue life and hardness of aerial aluminum alloy after laser shock peening are an alyzed.
