摘　　要：通过润湿性实验、钎焊接头性能实验,系统地研究了95Al_2O_3和Kovar合金在不同形态Ag-Cu-Ti活性钎料作用下的润湿钎焊机制.实验发现钎焊合金与陶瓷发生了界面反应,生成Ti_3Al、TiAl等相.采用Ag-Cu—5Ti非晶钎料时,接头四点弯曲强度可达270MPa.In this paper, the bonding mechanism of Ag - Cu - Ti Series active brazing fillers applied to 95 A12O3 - Kovar joint is studied by wettability experiments and mechanical properties of joint. The result shows that the interface reaction products of TiAl and Ti3Al exist between the brazing filler and ceramic. The four- point bending strength of 270MPa is reached using Ag- Cu- 5Ti amorphous alloys.
