When the stainless steel became passivated, the potential of the couple shifted towards positive and then resumed normal galvanic corrosion condition. 随着不锈钢表面的钝化,电位朝正方向移动,然后回复到通常的电偶腐蚀行为。
Traces of platinum microparticles dispersed in polyaniline film could result in a stable corrosion potential of stainless steel within the passive range. 分散在聚苯胺膜中的极少量铂微粒能使不锈钢板的腐蚀电位稳定在钝化区域。
