Abstract

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.

摘要

通过线性电位扫描和恒电流脉冲法研究了锡、Sn8Hg（γ2）相和牙科汞合金在氯化物溶液中的阳极行为。结果表明，阳极电流随氯化物浓度而变化，并且在电极钝化之前就发生了溶解。牙科汞合金钝化所需的阳极电荷量最小。
