摘要: 用相敏检波法测定了铝在氯化物溶液中当用约300μA/cm~2～30mA/cm~2电流密度阳极极化时的表面阻抗。结果表明lgRf(法拉第阻抗)与lgi(阳极极化电流密度)成线性长系,电容C与i成线性关系;证实了铝阳极溶解时活性溶解区的面积是外加阳极极化电流的线性函数,真实电流密度实际上并无变化,因此电位也无变化。

Abstract：The impedance of aluminum polarized in a chloride solution by a series of anodic current densities from approximate 300μA/cm~2 to 30 mA/cm~2 was determined using a phase sensitive detector.The results show that the relation between log R_f (Faradaic resistance) and logi (applied current density) appears as a straight line with a slope equal to tg (-45°) and the relation between capacitance C and i also appears as a straight line.These results support such a proposition that the active area during anodic dissolution is a linear function of the applied anodic current while the real anodic current density remains practically unchanged so that the potential is also unchanged.
