钎焊

In the BPW,a brazing filler metal,which has high melting point and is able to dissolve the base metal significantly,is placed between the faying surface to be joined,the assembly is heated with high frequency induction heating,and a high uniaxial pressure is applied to discharge the molten interlayer ...

BPW新工艺以熔点较高并能显著溶解母材的钎料为中间层，利用感应电源加热并施加较大的压力，挤出液态中间层及氧化膜等形成的夹杂物，最终在焊接面周边形成圆滑过渡的钎角，同时，在界面处实现洁净母材之间直接接触的固相压力焊接合。

On the other hand, if Ti foil is too thick, the interfacial reaction between liquid Cu-Ti alloy and Al〓O〓 ceramic can proceed sufficiently, due to the widening of the liquid phase region. This results in a too thick reaction layer, which also reduces the joint strength. Further more, in this situation, not all of the liquid alloy is isothermally solidified, similar to the case of brazing, the heatresistant of joint can't be improved.

相反，Ti箔过厚，一方面由于液相区宽度增大，连接过程中始终为Cu-Ti液体合金与陶瓷反应，导致形成过厚的反应层，降低接头强度；另一方而，由于连接后液相区未能完全等温凝固，与活性钎焊相类似，接头耐热性也难以得到提高。
