采用阳极键合法对玻璃/铝多层结构层间连接进行试验,通过SEM、EDS分析玻璃/铝多层结构键合界面的显微组织。结果表明:对连接接头进行拉伸试验时,断裂发生在玻璃基体中,这表明键合界面的结合强度高于玻璃基体;界面由过渡层组成,且过渡层元素呈梯度分布,过渡区主要为Al2Si O5复合氧化物。分析认为键合界面处复合氧化物Al2Si O5的形成是实现玻璃/铝界面连接的主要原因。
The bonding between the glass / aluminum multilayer structure was tested by anode bonding method. The microstructure of the glass / aluminum multilayer bonding interface was analyzed by SEM and EDS. The results show that the fracture occurred in the glass matrix during the tensile test of the joint, which indicates that the bond strength of the bond interface is higher than that of the glass matrix. The interface is composed of the transition layer, and the transition layer elements are gradient distribution. The transition region is mainly Al2Si O5 composite oxide. It is considered that the formation of Al 2 Si O 5 at the bonding interface is the main reason for the glass / aluminum interface connection.
