【Abstract】 The zirconia ceramic with Kovar 4J28 alloy were brazed by Au-Cu-Pt alloy solder belt. The brazing sintering curve was designed, and the influencing factor on joint strength were discussed at the best sealing temperature. Then, the interface combination status between ceramics and Kovar 4J28 alloy was analyzed. Results showed that the zirconia ceramic with 4J28 Kovar alloy were brazed at the temperature of 1040℃ and holding 20 min. By this way, the brazing sample could withstand maximum shear strength of 85 MPa. When the pressure difference is 60 k Pa, the leakage brazed sample is amount of 0.0 m L/min.更多还原
