摘　　要：分别研究了结构钢-玻璃-可伐合金系统的封接温度、封接时间和氮气流量对封接性能的影响,通过对接插件润湿性、气密性和结合强度的测试确定了熔封工艺的最佳工艺参数。结果表明:最佳封接温度为960℃,封接时间10 min,氮气流量2.5 m3/h,封接中间过渡层铁元素富集,金属与玻璃形成互锁结构,明显改善接插件的耐压性能。Influence of the sealing temperature, sealing time and nitrogen gas flow among structural steel- glass-kovar system on the sealing properties was studied separately. The optimum process parameter was confirmed by testing wettability, lightness and bonding strength. The result shows that： the optimum sealing temperature was 960 ~C, sealing time was 10 min, nitrogen gas flow was 2.5 m3/h. Iron element enriched in sealing center transition layer. An interlocking structure formed between metal and glass which improved pressure resistance obviously.
