通过椭偏,恒电位阶跃,恒电位阴极还原,动电位扫描手段,研究了不同幅值方波的交变电场对321不锈钢钝化膜性质的影响。实验结果表明,交变电场不仅能提高钝化膜厚度。改变钝化膜的电化学参数,提高钝化膜耐还原溶解能力,在一定的幅值条件下,还能提高钝化膜的点蚀破裂电位。
Systematic investigation of the effect of alternating voltage (AV) modulation on the features of the passive film on 321 stainless steel has been carried out by means of ellipsometry, potential step and potentiostatic reduction methods. Results of the investigation show that AV modulation increases the thickness and the resistance against cathodic reductire dissolution of the passive film. The parameters of impedance of the passivated electrode is also changed by the AV modulating passivation. An increase of breakdown potential (E_b) of the passive films can be achieved to some extent under certain AV conditions.
