摘　　要：对应用于高温高压环境的几种特殊不锈钢合金与玻璃材料进行了密封工艺研究,分析了玻璃与合金的封接工艺对其气密性和密封强度的影响。结果显示,通过控制工艺,采用该耐高温高压玻璃进行封装,其封装质量优异,封装强度高,室温绝缘性能>1000MΩ/500VDC,并能承受200MPa压力无泄漏。The research of the sealing process were carried out on some special stainless steels and sealing glass which used in high temperature and high pressure environments. The effects of the sealing process on its tight- ness and seal strength of the sealing glass and alloys were analyzed. The results show that the seal components endowed excellent sealing quality and compressive strength by means of the high-temperature and high-pressure resistance glass. Its insulation is more than 1000MΩ/500VDC at room temperature and can be not leak at the high pressure of 200MPa.
