Evaluation of the protective performance of a series of coatings composed of epoxy resin and certain amount of Al powder added has been made by means of electrochemical impedance spectroscopy and corrosion potential monitoring with emphasis being laid on the influence of the content of Al powder upon the protectiveness of the organic coatings for carbon steels in 3.5%NaCl aqueous solutions. It is indicated that the introduction of appropriate amount of Al powder into the organic coatings leads to a great enhancement of the protective property of the coatings (such as their capability against water penetration) while excessive addition of Al powder is pernicious to the property of the coatings, e, g. weight content ratio of the Al powder (V_(Al))over 30% is found to be detrimental. From our experimental results, optimal weight content ratio of the Al powder is 15%.
