对电真空钎料溅散性的各种影响因素进行分析对比 .结果表明 ,影响电真空钎料溅散性的主要原因是原料中含有氧、回炉料中含有CuO和Cu2 O ;采用 2～ 3次高真空重熔是解决电真空器件用贵金属钎料溅散性问题的根本方法
The results show that the main reason that affects the electric vacuum brazing material splashing is that the raw material contains oxygen and the back charge contains CuO and Cu2O; Secondary high vacuum remelting is the fundamental method to solve the problem of splashing of precious metal brazing filler for vacuum devices
