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.
