摘要
对石英玻璃等非金属材料与金属材料的几种封接技术进行了介绍。初步分析了封接过程中的重要环节应当采用的工艺手段,列举了各种封接方式的优缺点,介绍了帽罩封接方式新工艺和钼箔封接方式等的改进方法。以期在现有技术基础上,进一步完善光源的封接技术,逐步提高产品的真空气密性、热稳定性、机械强度等可靠性指标和使用寿命。
Several sealing-in technologies about nonmetal materials such as quartz glass etc. and metal materi- als are introduced. The process used in the important sealing-in process is preliminarily analyzed, merits and demer- its of various kinds of sealing-in modes are listed and the new process of calotte sealing-in mode and improvement method of molybdenum foil sealing-in mode are introduced. So on the basis of present technology, the sealing-in technology of light source is improved and relative reliability specifications of products such as vacuum-tightness, heat stability and mechanism strength etc. and operation lifetime are improved gradually.
