Acceleration of corrosion of dental amalgam by abrasion.
Dental amalgam shows passive behavior, but the protective film can be destroyed by abrasion. In this study, specimens of both low- and high-copper amalgam were abraded, and the effect on the corrosion behavior was examined. The electrochemical measurements showed that the corrosion rate was substantially increased, and that re-passivation was relatively slow.
