This investigation was undertaken to elucidate the electrochemical reactions involved in the in-vitro corrosion of silver, copper, tin and dental silver alloys in phosphate containing solutions. The galvanostatic method was used to compare the charging and discharging curves of silver, copperand tin with those of the alloys in the phosphate solutions. The formation of silver or cupric phosphate film on silver or copper in phosphate solutions occurred with anodic polarization and addition of chloride ions to the solution reduced the amount of film. The anodic polarization potential of tin or tin-containing dental silver alloy was very high and time dependent and greatly reduced by the addition of chloride ions, showing the inhibition of chloride ion to passivation of tin.
