Abstract
The effect of the passivation behavior of SAC305 alloy in deionized water on the structure and defects of the surface oxide film was investigated. The results indicate that during the passivation process of the alloy film formation, as the surface potential increases, Sn is oxidized, undergoing two transformations: first to Sn(II) and then to Sn(IV). During this process, the point defects in the oxide film evolve from Sn(II) interstitial ions and O vacancies to Sn(II) ion vacancies, and subsequently to Sn(II) and Sn(IV) interstitial ions and O vacancies. Additionally, the oxide film does not cover the Ag3Sn phase, yet the alloy is able to maintain an effective passivation.
期刊介绍:
Applied Surface Science covers topics contributing to a better understanding of surfaces, interfaces, nanostructures and their applications. The journal is concerned with scientific research on the atomic and molecular level of material properties determined with specific surface analytical techniques and/or computational methods, as well as the processing of such structures.
