英文摘要	The corrosion effect by Ag addition to Sn solder has been explored with consideration of the formed surface oxides film. Results indicate that the oxides film on Sn-Ag solder maintains a much shorter duration to NaCl electrolyte attack than that on pure Sn solder. The film thickness variation among phases of Ag3Sn and beta-Sn and the defects especially at boundaries facilitate Cl- preferential adsorption. After the oxides film deterioration, galvanic effect between Ag3Sn and beta-Sn comes into play for further corrosion. This observed evolution behavior provides a practical perspective to corrosion of Ag-alloyed Sn solder with an oxides film covering. (C) 2021 Elsevier B.V. All rights reserved.
