Abstract
New experimental evidence shows that most “corrosion sites” observed on CASS tested panels are sites of cathodic activity during the initial stages, and that the anodic areas are probably largely confined to the edges in the early part of the exposure. Most of the deterioration is due to action of high pH run-down associated with cathodic activity. Continued cathodic activity and consequent deterioration of the anodic coating produce additional anodes in the immediate vicinity of many of the cathodes. Surface impairments, metal defects, and conditions of aging between finishing and testing affect the amount of deterioration during CASS exposure.
