Abstract

The blistering of epoxy coating and its evolution were investigated after being exposed to 3.5 wt% NaCl solution. The evolution of under-film corrosion could be divided into four stages according to the observation of the corrosion morphology and the distribution of corrosion products and elements. Corrosion propagation was related to the distribution of media at the edge of the blistering area. Local electrochemical impedance spectroscopy analysis revealed that local impedance mapping could help in predicting the direction of corrosion propagation. The interfacial debonding at the edge of the blistering area was a necessary condition for corrosion propagation.
