| 摘 要： | 采用周模型计算分析了Sn-Ce-Me(Me=Pb、Bi、zn、Sb、Ag、Cu、Cd)三元合金系中，Ce与Sn以及Ce与Me之间的活度相互作用系数。计算结果表明，不仅在Sn-Pb-Ce中，Ce存在“亲Sn”现象，在其它6个三元无铅钎料合金体系中，如Sn-Bi-Ce、Sn-Sb-Ce、Sn-zn-Ce、Sn-Cd-Ce、Sn-Ag-Ce、Sn-Cu-Ce，Ce也同样存在着“亲Sn”现象。其研究结果可为新型无铅钎料的研究提供理论分析依据。

| Abstract: | The activity interaction parameters between Ce and Sn or Me in Sn-Ce-Me ternary alloy systems(Me=Pb,Bi,Zn,Sb,Ag,Cu,Cd)are calculated and analyzed by means of Chou model. The calculating results show that Ce have high affinity with element Sn not only in Sn-Pb-Ce ternary alloy system, but also in Sn-Bi-Ce,Sn-Sb-Ce,Sn-Zn-Ce,Sn-Cd-Ce,Sn-Ag-Ce,Sn-Cu-Ce ternary alloy system. The results will provide foundations for theoretical analysis for developing new lead-free solder alloys. |
