摘　　要：通过向Sn-Zn系钎料中添加从稀土废泥中提取出的自制混合碳酸稀土,比较添加混合碳酸稀土与添加混合镧铈稀土对Sn-Zn系钎料的抗氧化性、焊接可靠性和力学性能等的影响。研究结果表明碳酸稀土与混合镧铈稀土相比对于钎料的抗氧化能的改善作用更加有效;当碳酸稀土添加量为0.09%时,钎料的焊接界面金属间化合物层最薄;碳酸稀土相比混合镧铈稀土对于钎料的焊接可靠性能的改善更加明显;对于钎料的硬度改善更加有效。Homemade mixed rare earth carbonate extracted from rare earth waste mud was added into the Sn-Zn series solder. Influence of adding mixed rare earth carbonate and LC （ lanthanum - cerium rare earth） on the oxidation resistance, welding reliability and mechanical properties of solder were studied. The results show that mixed rare earth carbonate improves more of sorder oxidation resistance than LC. When the content of the rare earth carbonate is 0.09% ,the welding interface in- termetallie layer of the solder is the thinnest ;And also, rare earth carbonate has more obvious improvement on welding relia- bility and hardness of the sorder than LC.
