摘要
以Sn-9Zn-2Cu为研究对象,采用合金化的方法考察不同含量的Al元素对其微观组织及性能的影响。发现Al元素的加入可以较大地提高钎料的润湿性和抗氧化性。当w(Al)为0.035%时,钎料润湿性最好,同时钎料的硬度最大;当w(Al)为0.01%时,钎料抗氧化性最佳;Al元素的加入稍微提高了合金的熔点,主要集中在203℃左右;Al元素可以使合金组织细化,减小第二相尺寸,使其分散均匀化。
This article takes Sn-9Zn-2Cu as the object of study, inspecting A1 element of different contents to its microscopic organization and the performance influence using the alloy method. The re- search discovered that the A1 element may enhance the wettability and oxidation resistance of lead-free solders. When w（Al） is 0.035% , the wettability of solder is the best, and simultaneously the hard- ness is also the biggest; when w（Al） is 0.01%, the oxidation resistance is the best; the Al element also enhances the melting point of alloy slightly, mainly concentrated in about 203 ℃ ; the Al element may cause the alloy organization refinement, reduce the second size, and cause its disperser uniformization.
