| 摘 要： | 以定量研究微量添加元素Ａｇ，Ｉｎ，Ｂｉ，Ｓｂ对低Ｓｎ含量（１４Ｓｎ－余Ｐｂ）合金钎料表面张力的影响为理论基础，将钎料中微量元素的添加量、钎料的润湿性能及熔化温度等进行了三水平双指标正交试验，在综合考虑钎料的工艺性能、承载强度及工艺性能的基础上，对汽车、拖拉机等内燃机中铜质水箱散热器钎焊用低Ｓｎ含量Ｓｎ－Ｐｂ钎料的成分进行了优化设计。

| Abstract: | In this investigation, based upon the quantitative study of the influence of microadding elements Bi,In,Ag and Sb on surface tension in low tin content tin-lead based alloy solders, the cross-method tests have been carried out in three-level and double-targets for the adding content of microadding elements,wettability and the upper melting point of solders. The optimal design of composition on low tin content tin-lead based solders used for soldering the radiators of automobiles and tractors has been determined on the basis of comprehensive consideration among the economy,technological properties and strength of the solders. |
