Dip brazing is a brazing process suitable for common aluminium microwaveassemblies.The base metal was the Chinese commercial aluminium alloy LF21(similarto 3003).Brazing filler metals used were A1-11.5Si-1.5Mg and AI-7Si-1.5Mg.The parts were brazed at 605—615℃(1121—1139°F)in a vacuum of 1×10~(-5)Torr(1.3 mPa).Experiments showed that the oxide film of aluminium could not beremoved during the vacuum brazing process,the molten brazing filler metal spreadalong the oxide/metal interface,with oxide film was lifted...

Dip brazing is a brazing process suitable for common aluminium microwaveassemblies.The base metal was the Chinese commercial aluminium alloy LF21(similarto 3003).Brazing filler metals used were A1-11.5Si-1.5Mg and AI-7Si-1.5Mg.The parts were brazed at 605—615℃(1121—1139°F)in a vacuum of 1×10~(-5)Torr(1.3 mPa).Experiments showed that the oxide film of aluminium could not beremoved during the vacuum brazing process,the molten brazing filler metal spreadalong the oxide/metal interface,with oxide film was lifted and floating on thesurface of molten brazing filler metal.Thus during vacuum brazing of aluminiumthe capillary attraction was weak and the continuity of brazing joints was poor.Inorder to increase the capillary attraction and to obtain continuous fillet of brazingfiller metal,local roughening of the surface of the parts to be brazed was performed,a technological cover was placed over the assemblies in vacuum container,and acertain amount of Mg-chips was put into the cover.Experimental results have provedthe effectiveness of the new process:the wetting and spreading of brazing fillermetal were very good,the flow distance and clearance fillability were raised upabout 2 times;and the microwave assemblies having complicated configuration werebrazed in one heat successfully,free from corrosion and distortion,so neither cleaningnor readjusting operation after brazing were needed.

试验证明,铝波导滤波器的理想钎焊方法是真空钎焊。基体材料为LF21铝合金。钎料为Al-11.5Si-1.5Mg 和Al-7Si-1.5Mg。部件的钎焊温度为605~615℃,其真空度为1×10~(-5)Tor,试验指出,在真空钎焊时,铝的氧化膜并不能去除,熔化钎料是沿着金属和氧化膜之间的界面铺展的,氧化膜被举起,熔化钎料沿铝表面流动。因此,毛细作用微弱,且不能很好地形成连续的钎缝。为了提高毛细作用和得到连续的圆角,部件表面进行了局部打磨,而在真空腔内放置了“工艺罩”,在罩内放置了适当量的镁块。试验证明这是有效的:钎料的润湿和铺展非常好;流动距离和填充间隙能力提高了两倍;而组合件一次可以满意地焊成,且不会产生腐蚀和明显变形,从而不需焊后清洗和修整.
