Research on bonding test of 5052 aluminum alloy based on laser texturing technology
-
摘要: 为了提高5052铝合金的粘接性能，利用脉冲光纤激光的短脉冲和高峰值功率的特性，对铝合金试件进行了激光毛化试验研究。通过正交实验法，研究了平均功率、扫描速度、脉冲频率和脉冲宽度等工艺参数对激光毛化质量的影响，以及各工艺参数的影响权重，并求得最佳工艺参数，最佳工艺参数为平均功率90 W、扫描速度10 mm/s、脉冲频率1000 kHz、脉冲宽度200 ns。根据优化后的工艺参数，加工获得了粗糙度2.35 μm，然后对激光毛化后的铝合金试件进行单搭接拉伸试验，研究发现粘接强度随着粗糙度的增大而增大，当粗糙度到达一定程度时，粘接强度反而会随着粗糙度的增大而减小。另外，粘接强度还跟铝合金表面的微织构的类型及疏密程度都有很大关系。Abstract: To improve the bonding performance of 5052 aluminum alloy, the laser texturing experiment on aluminum alloy specimens was carried out by using the short pulse and high peak power characteristics of pulsed fiber laser. Through the orthogonal experiment method, the effects of process parameters such as the average power, scanning speed, pulse frequency, pulse width and other parameters on the quality of laser texturing, as well as the influence weight of each process parameter, and the best process parameters are obtained. The best process parameters are average power 90 W, scanning speed 10mm/s, pulse frequency 1000 kHz, and pulse width 200 ns. According to the optimized parameters, a good area with roughness 2.35 μm is obtained. Then a single-lap tensile test on the aluminum alloy specimens after laser texturing was carried out. The study found that the bonding strength would increase with the increase of roughness, when the roughness reached a certain level, the bonding strength would decrease with the increase of roughness. In addition, the bonding strength is also closely related to the type and density of the microtexture on the surface of the aluminum alloy.
