摘要
研究了添加不同含量Ag元素对铝软钎焊用Sn-1.5Zn系钎料合金的熔化特性、显微组织、润湿性及钎焊接头抗腐蚀性能的影响。研究结果表明,Ag元素的添加缩短了Sn-1.5Zn钎料的熔程,细化了显微组织;采用润湿平衡法测量结果发现,添加Ag元素提高了钎料对铝基体的最大润湿力Fmax,但使润湿时间t0增加;采用3%(质量分数)浓度盐水溶液浸泡焊点实验结果表明,添加Ag元素提高了钎焊接头的抗腐蚀性。
The influence of Ag addition on the melting characteristics,microstructures,wettability and corrosion-resistance of the Sn-1.5Zn based alloys for soldering aluminum was investigated.The experimental results show that Ag addition in Sn-1.5Zn based solder alloys decreases the melting point range and refines the microstructures;furthermore,the wetting balance test results manifest that the addition of Ag into Sn-1.5Zn increases the maximum wetting force（Fmax） of the solders,while increasing the wetting time t0;finally,it has been shown that the joints soldered by the Ag-added Sn-1.5Zn based alloys exhibit the increased corrosion resistance in 3%（mass fraction） NaCl solution.
