heal.abstract	Pretreated steel specimens coated with epoxy resin, either pure or containing iron powder, were exposed to a corrosive environment (aqueous 3.5 wt-%NaCl solution). Data concerning the modification of their properties were recorded via electrochemical impedance spectroscopy measurements at medium and high frequencies. Analysis of time dependent elements of proposed models has enabled the individual contributions to the impedance of the phases created during immersion to be distinguished and changes in the behaviour of the coatings due to water uptake to be monitored. These results, together with water permeability and hardness measurements and visual analysis, have revealed minor differences in the performance of the metal filled coatings compared with those of the pure epoxy.
