摘要
设计制备了不同成分的5种锌铝药芯钎焊丝,对锌铝药芯钎焊丝的制备工艺及其在紫铜和6063铝合金上的润湿性能进行了研究。结果表明,锌铝钎料成分对锌铝药芯钎焊丝的制备工艺性有明显影响,Zn80Al15Ag5、Zn92Al8和Zn95Al5这3种锌铝带状钎料制备的药芯钎焊丝质量较好;5种锌铝药芯钎焊丝在6063铝合金上均具有良好的铺展性;铝元素含量对锌铝药芯钎焊丝在紫铜上的铺展性能影响较大,在该试验范围内,随钎料中铝元素含量的增加,钎料在铜上的铺展面积迅速增大,Zn72Al28药芯钎焊丝在铜上的铺展面积最大,达到86 mm^2。
Five kinds of Zn - Al flux cored wires with different compositions were designed and produced,and their manufacturing process and wettability on the surfaces of copper and aluminum alloy were studied.The result shows that the composition of Zn - Al brazing filler metals has an obvious influence on the manufacturing process of Zn - Al flux cored wire.The brazing filler metals of Zn80A115Ag5、Zn92A18 and Zn95A15 have better quality.These five kinds of Zn - Al flux cored wires have good spreadability on 6063 aluminum alloy.The content of aluminum in Zn - Al flux cored wire has great effect on the spreadability on copper.With the increase of the content of aluminum in the brazing filler metals, its spread area on the copper will increase rapidly.Zn72A128 can get the largest spread area on the copper,which can be up to 86 mm.
