A large number of standardized test methods for cathodic disbonding are available. Parameters like voltage, electrolyte composition, temperature, sample configuration etc vary over a wide range between the various tests. A round robin test recently organized by NACE showed that one can expect significant variation in result between test labs, in spite of identically coated samples and test procedures. This paper presents a review of published literature on the effect of various parameters on cathodic disbonding, and results from a study on the effect of oxygen concentration, dry film thickness, applied potential and electrolyte composition on cathodic disbonding. The objective with the paper is to
discuss the importance of various test parameters on cathodic disbonding results: Electrolyte composition, presence of hypochlorite in the electrolyte, applied potential, dry film thickness, and oxygen concentration in the electrolyte.
