Polarization behavior of dental amalgams in 50mM hydrogencarbonate solutions containing sodium chloride were studied by the potential sweep method with sweep rates of 200 and 50mV/s. The dental amalgam electrodes studied were prepared from a conventional amalgam alloy and three high-copper amalgam alloys according to the manufacturers' instructions in regard to mercury-alloy ratios and trituration times. The electrochemical behavior of conventional and high-copper amalgam electrodes in the hydrogencarbonate supporting electrolyte solutions were relatively inactive as compared with in sodium chloride supporting electrolyte solution. The addition of chloride increased currents for oxidation of tin or silver in conventional amalgam. Potential sweep polarization curves for the high-copper dental amalgam in supporting electrolyte solutions exhibited an anodic current peak due to the oxidation of copper and the peak current increased with the addition of chloride to the solution.
