用化学成分分析、力学性能测试及显微组织观察等手段,分析了复合板爆炸焊接失效的原因。结果表明,由于间隙中气体未能全部排出,造成复合板结合面积率低;基板边缘翘皮现象系爆炸焊接的边界效应,是爆炸能量过大引起的伤裂现象。针对失效问题提出了相应的改进措施。 With chemical composition analysis, mechanical properties testing and microstructure observation and other means, analysis of composite plate explosion welding failure causes. The results show that the bonding area ratio of the composite board is low due to the incomplete discharge of the gas in the gap. The boundary effect of the warping on the edge of the substrate is the explosive effect caused by the excessive explosion energy. Aiming at the problem of failure, some corresponding improvement measures are put forward.
