The main cause of coating degradation on pipelines with CP is cathodic disbondment To provide useful guidance for selecting pipeline coating systems, cathodic disbondment test methods (categorised as standard test methods or modified test methods) that have been developed over the past two decades have been critically reviewed in this article.
In-situ techniques for assessing cathodic disbondment of coatings, especially those having promise for field applications, are also discussed. Finally, a brief discussion on the mitigation of cathodic disbondment and the associated corrosion is given. This review was published in Progress in Organic Coatings, Volume 146, September 2020.
