The effect of laser peening is related to power of laser, spot size of laser, material mechanic property and so on.
激光喷丸的效果与脉冲的能量、光斑直径的大小、材料的力学性能等因素有关。

Using of pre-drawing, extruding holes and shot peening techniques has shown obvious effect in extending the fatigue life of motorcycle chain.
用预拉、挤孔、喷丸等强化工艺来提高摩托车链条的疲劳寿命效果很明显；
3
After shot peening, the regular fatigue strength of aluminium alloy can be increased and the effect of micromotion on fatigue performance of ther material can be avoided.
