激态原子发射激光可用于处理预粘接的铝合金件．该方法提供了一种可代替包括常规阳极化处理等对生态环境不利的化学方法．实验结果表明，同未处理的基体和经阳极化处理的基体相比，粘接前用激光处理表面能大大改善改性环氧树脂粘接铝试件的剪切强度．从能量约为０．２焦尔／脉冲／平方厘米的激光取得了更好结果，这时同未处理的铝合全相比单搭接剪切强度增加６００—７ｏ０％，网铬酸阳极化预处理相比单搭接剪切强度增加４０％．在处理过程中随着激光脉冲数的增加破坏方式从粘果破坏变为内聚破坏．内聚破坏现象归因于用电子显微镜双侧的形态改变，也归因于俄歇电子能谱及红外光谱表明的化学改性．可见，将激光用于铝合金的粘接预处理方面具有精确，方便和无污染等优点．
Excimer laser can be used to process pre-bonded aluminum parts. This method provides a chemical method that can be detrimental to the ecological environment instead of conventional anodization. Experimental results show that laser treatment of the surface prior to bonding significantly improves the shear strength of modified epoxy bonded aluminum specimens compared to untreated substrates and anodized substrates. Better results were obtained with lasers having an energy of about 0.2 Joules per pulse per square centimeter when the single lap shear strength was increased by 600-7o0% compared to the untreated aluminum alloy, Compared with single lap shear pretreatment increased by 40%. In the process of treatment with the increase in the number of laser pulses the damage from cohesive failure to cohesive failure. Cohesive failure is due to morphological changes on both sides of the electron microscope, also due to chemical modification by Auger electron spectroscopy and infrared spectroscopy. Can be seen, the laser used for bonding aluminum pretreatment has the advantages of precision, convenience and pollution.
