采用多道激光透射封接技术, 对大尺寸3.3高硼硅玻璃-可伐合金封接工艺进行了探索性研究, 采用正交实验方法, 实现了两种材料的可靠封接。确定了优化工艺参数：扫描速度为25mm/s, 激光功率为100W, 离焦量为+40mm, 扫描次数2次。通过使用SEM、EDX以及激光共聚焦显微镜观测硼硅玻璃-可伐合金的激光封接断面, 对比相图, 就结合界面的特征和机理进行了初步分析, Fe2SiO4化合物的形成是两者能够可靠封接的主要原因, 确定了两种材料的激光可封接性。

The joining behavior and interface analysis of Pyrex Glass-to-KOVAR Alloy with fiber laser were studied in the paper. By the orthogonal experiment method, the optimized parameters of laser joining were obtained: scanning speed of 25mm/s, laser power of 100W, defocus distance of +40mm, scanning number of 2. The fractures graphs were observed by LEXT OSL 3000. By analyzing the FeO-SiO2-Fe phase diagram, SEM and EDX on the fractures, it displayed that a new chemical substances (Fe2SiO4) had formed which was considered as the key-materials for a good glass-to-KOVAR alloy joint.
