The present work investigates the passive film formation and properties on tin and tin solder alloys in weakly acidic nitrate solution by using conventional electrochemical methods as well as electrochemical impedance spectroscopy and Mott-Schottky analysis. It is observed that the influence of the main alloying elements, antimony and copper, positively influences the formation and properties of native oxide films on the respective alloys. If the oxide film is anodically formed, the process can be interpreted as a high-field mechanism. In this case, antimony, as well as copper, increases the electron conductivity of the anodic formed layers analogous to the transparent conducting oxide layers (e.g., ATO layers).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
