The results show that, Au-19.25Ag-12.80Ge brazing alloy is better, its melting temperature range is 446.76494.40 ℃, and the temperature interval between the solidus and the liquidus is 47.64 ℃. When the brazing temperature is in the range of 510550 ℃, the alloy has a good spreadability and wettability with Ni. Interface structure observation reveals that there is one continuous intermetallic layer between the brazing alloy and the base metal Ni when welding. X-ray energy spectrum analysis results show that the intermetallic layer is Ge3Ni5, and because of its brittleness, the overthick intermetallic layer will decrease the shear strength of the welding joint, therefore, the welding technology should be controlled so as to gain an ideal welding interface structure.

研究结果表明：Au-19.25Ag-12.80Ge合金的性能较好，其熔化温度范围为446.76~494.40 ℃，结晶温度区间为47.64 ℃；焊接温度在510~550 ℃范围内时，Au-19.25Ag-12.80Ge钎料合金与Ni基体具有良好的铺展性和润湿性，焊接时钎料合金与Ni基体之间形成了一条连续的金属间化合物层，能谱分析表明该金属间化合物层为Ge3Ni5，由于该化合物较脆，过厚的金属间化合物层使焊接接头的剪切强度下降，故应适当控制焊接工艺以获得理想的焊接界面组织。
