Abstract
The effect of addition of aluminum (Al) nanoparticles to epoxy coating on the ability to protect the carbon steel was studied by electrochemical impedance spectroscopy and focused ion beam-transmission electron microscopy. The EIS was conducted in 0.1M NaCl solution after wet/dry cyclic corrosion test. The addition of Al nanoparticles increased the film resistance (R f) and the charge transfer resistance (R ct) of epoxy-coated steel. The surface analysis showed that uniform and fine Al-Fe complex oxide layers were formed acting as barrier layers that enhanced the corrosion protection of the epoxy-coated steel. It has been concluded that the Al nanoparticles had a beneficial role in improving the corrosion resistance of the epoxy-coated steel.
