Polarization behavior of dental amalgams in 0.86% sodium chloride solutions were studied by the potential sweep method with a sweep rate of 200mV/s. anodic potential scan limits of 0.0V (SCE) or -0.5V (SCE), and cathodic potential scan limit of -2.5V (SCE). The dental amalgam electrodes studied were prepared from two conventional amalgam alloys and three high-copper amalgam alloys according to the manufacturers' instructions in regard to mercury-alloy ratios and trituration times. The hydrogen evolution reaction from water molecules (HERW) was not affected by the anodic potential scan limits. The hydrogen evolution reaction from hydrogen ions (HERH) occurred at potentials below -1.0V (SCE) in the solutions containing 15mM hydrochloric acid and it had little effect on HERW. Under this experimental conditions, HERH did not occur with anodic potential scan.
