摘　　要：采用Au-Cu-Pt合金钎料带,对氧化锆陶瓷与Kovar 4J28合金进行了钎焊研究,探讨了钎焊温度和保温时间对接头强度的影响,并分析了氧化锆陶瓷与4J28合金的界面结合情况。结果表明,氧化锆陶瓷与Kovar 4J28合金在1040℃保温20 min焊接,得到的焊接器件能够承受最大的剪切强度为85 MPa;在压力差为60 k Pa时,封接器件不泄漏。The zirconia ceramic with Kovar 4J28 alloy were brazed by Au-Cu-Pt alloy solder belt. Thebrazing sintering curve was designed, and the influencing factor on joint strength were discussed at thebest sealing temperature. Then, the interface combination status between ceramics and Kovar 4J28 alloywas analyzed. Results showed that the zirconia ceramic with 4J28 Kovar alloy were brazed at thetemperature of 1040℃ and holding 20 min. By this way, the brazing sample could withstand maximumshear strength of 85 MPa. When the pressure difference is 60 kPa, the leakage brazed sample is amount of0.0 mL/min.
