A cathodic delamination study of coatings with and without mechanical defects

2014

It has been demonstrated that the surface defects of carbon steel, when protected with a coating in good conditions, cause an advance of the cathodic delamination front as fast as that caused by forced cathodic polarization where the coating is damaged. For this and because the potential difference between cathodic and anodic areas in the crevice corrosion process is much smaller than the polarization promoted by the anodic areas beneath the damaged coating, it is suggested that diffusion prevails over migration as controlling parameter in the forward speed of the process. Trending were confirmed by Scanning Kelvinprobe and Scanning Vibrating Electrode Technique. © 2014 Elsevier Ltd.
