Based on the characteristic of thin aluminium skin, shot peening and peening forming, peening forming by double face is a new mixed process.
对喷成形技术是结合铝合金薄板件的特点，在喷丸成形和强化工艺基础上，提出的一种边缘工艺技术。
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.
铝合金经喷丸强化处理后，可将常规疲劳强度提高，并使材料的疲劳性能不受微动作用的影响。
This is the result of a 4 kJ shot with a mini wrench above the aluminium, which leaves a sharp impression except in the centre where the work coil does not cover.
这是由于4千焦拍摄一场小型扳手高于铝，其中留下了鲜明的印象，除了在中心工作的线圈并不涵盖。
