Paper Abstract

A fundamental study on evaluating an epoxy-based coating was conducted. The study aimed to determined the performance of the coating on a low carbon steel as a result of chemical contaminations. Coated samples were tested in a local tap water by using the method of real time— holographic interferometry. A mathematical model was used along the obtained experimental data. The model described processes of detecting the early corrosion of the the steel under the coatings by holographic interferometry. Consequently, the holographic interferonxetry technique was found very useful in detecting the early corrrosion processes of the coated steel Also, a relationship between the displacement of the coating ,dueto metal corrosion under the coating, and corrosion current density of the coated steel was established for the epoxy-based coating with and without an addition of sodium chloride to the coating.
