Potential sweep and intensiostatic pulse studies of Sn, Sn8Hg and dental amalgam in chloride solution

The anodic behavior of the Sn, the Sn8Hg (gamma2) phase and the dental amalgam in a chloride solution has been investigated by means of the linear potential sweep and of the intensiostatic pulse method. The results indicate that anodic current varies with chloride concentration and that dissolution occurs prior to passivation of the electrode. The anodic charge needed for the passivation is smallest for the dental amalgam.
