摘要

Sn-0.7Cu共晶焊料长期面临的挑战是，添加合金元素会导致腐蚀性能下降。本文报道了一种从30种备选元素中筛选具有耐腐蚀遗传元素的Sn-0.7Cu型焊料的新设计方案。结果表明，经济型的Al、Zn和Ni是潜在的候选遗传元素。加入遗传元素后，应变能减小。腐蚀裂纹难以沿界面打开、扩展和传播。本研究结果为提高多元素锡基合金钎料的耐蚀性提供了可行的策略。

Screening corrosion-resistant genetic elements of Sn-0.7Cu solders by high-throughput calculations

The long-term challenge faced by Sn-0.7Cu eutectic solder is that the addition of alloying elements can lead to a decrease in corrosion performance. Herein, we report a new design scheme for screening Sn-0.7Cu type solders with corrosion resistant genetic elements from 30 alternative elements. The results indicate that economical Al, Zn and Ni are potential candidate genetic elements. After the adding genetic elements, the strain energy decreases. Corrosion cracks are difficult to open, extend, and propagate along the interface. The present findings may provide a feasible strategy for improving the corrosion resistance of multi-element Sn-based alloy solders.
