An overview of techniques for characterizing inhomogeneities in organic surface films and underfilm localized corrosion

This paper presents an overview of techniques for characterizing inhomogeneities in various forms of organic surface films including organic coatings, corrosion inhibitor and anti-corrosion oil films, and for understanding the effects of surface film inhomogeneities on underfilm localized corrosion. Particular focus is on technological innovations that have been made over the past two decades, including scanning probe techniques and the wire beam electrode method. (C) 2013 Elsevier B.V.
