- Abstract
- Organic coatings are the most widely used means of protecting metals against corrosion. Despite improvements in coating technologies, problems continue to exist in protecting metals from their environments. Considerable research on the degradation of coated metals has been done and significant advances in understanding the mechanisms and mode of failure of these materials when exposed to a corrosive environment have been made. However, there has been little work to quantitatively describe the degradation and predict the performance of a coating/metal system during service. This paper presents two mathematical models which have been developed to describe the degradation of an intact coating on a steel substrate exposed to an electrolytic environment. This paper is a contribution from NIST to honor Dr. Ray Dickie for his outstanding research on protective coatings and his significant contribution to the understanding of the degradation or organic protected metals.
