Steel specimens were coated by a spinning process with a layer of polymeric particulate composite consisting of an epoxy resin matrix (DOW 331) and metal powders (Fe, Al, Zn) as filters. The applied coating had a thickness of 70μm. The corrosion performance of these composite coatings in 3.5% NaCl solution was investigated by Electrochemical Impedance Spectroscopy, Tafel measurements and Potential monitoring. Dielectric measurements were also undertaken in the frequency range 20 Hz -13 MHz. Interrelation of the obtained results demonstrates that the types of particulate composites tested provide systems with corrosion rates and steady state impedance values in the same range of order of the pure epoxy resin coatings. The metal powder addition does not worsen the protective performance of the coatings at least for the low content of metal fillers used. (EN)
