摘要
碳钢上的钝化膜为不均匀膜,其稳定性比纯铁的钝化膜低,并随酸度的降低和钝化时间的增长而增加。在0.8V钝化一个半小时后,开路电位衰减曲线出现两个平台。采用方波迭加法模拟了电流振荡现象。
The passive film on carbon steel is a uneven film, and its stability is lower than that on pure iron. It increases with decreasing acidity and increasing anodized time. There are two arrests on the open-circuit potential decay curves after 1.5 hr anodization at 0.8 V.The current oscillation has been simulated with the squarer potential addition method.
