通过钎剂、钎料、真空度、工装夹具和钎焊工艺等对铝合金真空钎焊质量的影响实验研究,明确了这些关键因素的影响机理,归纳出了钎焊工艺设计的关键点.工作压强≤1×10~(-3)Pa是铝真空钎焊的必要条件,尽可能减少工装的热容量是基本的设计原则.

The impacts of the vacuum brazing conditions,including the flux type,filler metal,base pressure,thermal properties of jig and set,and brazing technologies available,on the microstructures,chemical contents and mechanical properties of the aluminum alloy parts to be brazed were experimentally studied.The results show that among other things,the working pressure and thermal capacity of the jig-set strongly affect the vacuum brazing of aluminum alloy.We suggest that the working pressure lower than 1×10~(-3)Pa and a jig-set made of material with low heat capacity be the fundamental requirements for the vacuum brazing.
