Understanding the enhanced corrosion resistance of micro-alloyed SnAg solder based on surface native oxide film evolution
The refinement of Ag3Sn phase is traditionally taken as an important criterion to improve the corrosion resistance of SnAg solder. In this work, the effects of Zn and Ni addition on corrosion resistance of SnAg solder have been investigated. Results indicate that 0.5 wt% Zn addition greatly refines the size of Ag3Sn but lowers the corrosion resistance of SnAg solder. In contrast, 0.5 wt% Ni addition cannot refine Ag3Sn grains but can enhance the corrosion resistance of SnAg solder. It has been found that the micro-alloying induced surface native oxide film evolution is responsible for the observed corrosion resistance evolution. Therefore, it has been proposed that the alloying elements that can promote the formation of a stable and compact surface native oxide film are also of interest to corrosion resistance improvement, thus offering another consideration to develop corrosion-resistant SnAg solder.
