Abstract
Two aspects related to the deterioration process of organic coated str uctures under cathodic protection, detected in a previous work, are an alysed: (i) why the size of failures exposing the metallic substrate c an influence the level of delamination and (ii) if there is a failure exposing the metallic substrate, why the appearance of blisters is fos tered even away far from the original failure, The results show that a n improvement of laboratory procedures for coatings selection can cont ribute to the development of coating/cathodic protection technology. F inally, the limitations of usual cathodic protection criteria are disc ussed considering the impedance measurements of samples with electrode s placed at the coating/metal interface.
