Summary The influence of surface finishing procedures on the corrodibility of high‐copper amalgams was measured. Anodic polarization curves were determined in Ringer's solution for amalgam samples made from a dispersion and a ternary alloy. Three types of finishes were compared: as carved, burnished, and polished. The polarization curves of the burnished and polished specimens were statistically similar ( P > 0·05) at all potentials investigated. The carved samples exhibited higher corrosion currents at most of the potentials investigated.
