heal.abstract	Pretreated steel samples have been coated with a layer (similar to 250 mu m) of a metal-filled (Ni, Cu, Fe) epoxy resin (Dow 324) deposited by a spinning process. The corrosion behavior of these specimens in 3.5% NaCI has been investigated by electrochemical impedance spectroscopy, Tafel measurements, and dielectric measurements undertaken in the frequency range of 20-10(7) Hz. Correlation between the different approaches shows that coatings of epoxy resin composites filled with iron powder possessing higher ac resistance and lower capacitance are more protective than the pure epoxy resin coatings. On the contrary, copper or nickel powder addition leads to coatings which, though still protective, exhibit lower protection than the pure epoxy.	en
