摘要

In this study, the failure behavior of epoxy coating in 3.5% (mass fraction) NaCl solution was investigated by electronic speckle pattern interferometry (ESPI) and electrochemical impedance spectroscopy (EIS). We found that ESPI images changed with the diffusion of corrosion products and the appearance of defects such as blistering. Direct information can be obtained from the images taken at different times. The relation between impedance characteristics and ESPI images was investigated. Experimental results showed that ESPI is an effective technique to detect coating degradation, and it provides a comprehensive approach to studying the process of coating degradation and under-film corrosion.
