稳定钝化时，是具有一个时间常数的单容抗曲线；在孔蚀诱导期，低频区阻抗实部呈现电感性收缩现象；在孔蚀发展期，是具有两个时间常数的曲线。

The results show that the Ni-Fe coatings are acid-resistant to HNO3 and H2SO4.For Ni-Fe alloys without exfoliation,the EIS is composed by a capacitive arc at high frequency and an inductive arc at low frequency, and the radius of capacitive arc decreases rapidly and the inductive component weakens and disappears with time.

结果表明：Ni-Fe合金镀层具有良好的耐酸腐蚀性；在3.5wt%NaCl溶液中，腐蚀发生之前的镍铁合金镀层的电化学阻抗谱由一个高频容抗弧和一个低频的感抗弧组成；随着浸泡时间的延长，容抗弧半径快速减小，感抗弧减弱并消失。
