环氧涂料涂覆碳钢海水腐蚀检测研究

Organic coatings are widely applied to protect metals from corrosion. This work detected the corrosion of epoxy coating/carbon steel system in seawater by electrochemical spectroscopy impedance (EIS) using the developed detection probe. The aim of the work presented here is to develop an on-site corrosion detection system. Results show that the probe developed here is applicable in the electrochemical detection of the corrosion of organic coating coated carbon steel. This lays a foundation for the on-site corrosion detection of coated carbon steel in marine environment and helps better understanding of the mechanism of coating degradation and coating life prediction.
