摘　　要：在对激光冲击强化技术与喷丸表面强化技术比较分析之后,表明航空发动机叶片经过激光冲击强化后,能显著增加叶片表面残余压应力,提高疲劳性能,并且其效果优于喷丸表面强化技术。The techniques of laser shock processing and shot peening were analyzed. The plastic deformation of the treated aero-engine fan blades caused by the shock wave gives rise to compressive residual stresses to enhance the fatigue resistance of the treated material by using laser shock processing. The effect was better than by using shot peening.
