通过极化曲线和阻抗谱研究了铝在酸性和近中性溶液中的腐蚀行为。阻抗图显示至少三个时间常数或半圆，其大小取决于电极电位。这表明至少有三个潜在的依赖过程正在发生。高频下的电容时间常数可能与氧化膜本身有关。低频下的第二电容时间常数可归因于氧化膜的溶解。
Polarization and impedance measurements were performed to study the corrosion behaviour of aluminium in acidic and nearly neutral solutions. The impedance diagram shows at least three time constants or semi-circles of which the size are dependent on the electrode potential. This indicates that at least three potential dependent processes are occurring. The capacitive time constant at high frequencies may be related to the oxide film itself. The second capacitive time constant at low frequencies can be attributed to the dissolution of the oxide film.
