摘要
Electrochemical impedance spectroscopy (EIS) can provide a rapid and convenient method for evaluating the coatings' anti-corrosion performance, especially for analyzing the evolution of water diffusion. However, due to the coating/metal interfaces' limitation, the electrochemical reaction at interfaces is still not elucidated. Therefore, focusing on coating/metal interfaces, this paper investigates the coating failure mechanism on the coated X80-matrix with pure DGEBA coatings and the formation process of Fe3O4 at interfaces.
