根据Ag -Cu -Si相图及Si对Ag -Cu合金性能影响的研究结果 ,采用DTA法测定了含量为 2 0 %～ 45%Ag、 1 %～ 7%Si的Cu -Ag -Si系列钎料合金的固液相线温度 ,并对钎料的综合性能进行了试验研究。结果表明 :Ag为 2 5%～ 45%、Si≤ 3%以及添加微量Fe、Ni、Co组元的Cu -Ag -Si系列钎料、具有良好的塑性和钎焊特性 ,可以满足电真空器件和其它构件在 80 0～ 850℃及 92 0～ 950℃二级钎焊要求。
According to the results of Ag-Cu-Si phase diagram and the influence of Si on the properties of Ag-Cu alloy, the Cu-Ag-Si series brazing filler metal with 20% ~ 45% Ag and 1% ~ 7% The solidus and liquidus temperature of the alloy were tested, and the comprehensive performance of the solder was tested. The results show that the Cu-Ag-Si brazing filler metal with 25-55% Ag, Si ≤ 3% and trace Fe, Ni, Co components have good plasticity and brazing properties, And other components at 80 0 ~ 850 ℃ and 92 0 ~ 950 ℃ secondary soldering requirements.
