Acceleration of corrosion of dental amalgam by abrasion
M. Marek
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.
