Correlation between EIS and Potential distribution for carbon steel under epoxy coating

摘要：

　　The potential distribution of carbon steel under epoxy coating exposed to natural seawater was investigated by the wire beam electrode (WBE) technique.The electrochemical impedance spectroscopy (EIS) of the WBE was characterized to analyze the behaviour of the coating degradation and metal corrosion at coating/metal interface.The mechanism of coating degradation was discussed from a point of electrochemical distribution.This research showed that the potential distribution had a close relationship with the characteristic of EIS in local area.The combined method can help us better understand the mechanism of the organic coating degradation and beneath substrate corrosion.
