Abstract
Degradation of the carbon steel/alkyd coating interface is studied with a scanning vibrating capacitor technique. This method is shown to provide information on the state of the metal under the coating, that is, the nature of the metal/polymer electrical double layer, as well as the diffusion rates for water, oxygen, and ionic forms of electrolyte to the steel/alkyd interface. Processes of the hydrolysis of adhesion bonds, metal corrosion, and the polymer's cathodic delamination are investigated. The processes that limit corrosion of the metal under the coating are discussed. It was found that the metal activation and corrosion are determined, for the steel/alkyd system under study, by the oxygen diffusion flux through the polymer and by the formation of differential aeration couples under the coating.
