In this paper, the anticorrosive performances of fastener coatings containing PTFE and/or nano aluminum particles were investigated by using electrochemical impedance spectroscopy, scanning electron microscope. The impedance spectroscopy was interpreted by means of analysis equivalent electrical circuits. The coating capacitance of the films was monitored with the immersion time to establish the water and ions permeability of these paint films. By comparison with clear coating, PTFE and PTFE- nano aluminum pigmented coatings, the results indicated that PTFE lowers the protective properties of the waterborne epoxy film although it can provide lubricating effect. The nano aluminum powder presented the best beneficial effect and resulted in a significant increase in corrosion resistance of the PTFE- nano aluminum composite coatings. The corrosion-resistant mechanism of the effect of PTFE and nano aluminum particles in the coating is discussed.
