Abstract

Nanostructured Al2O3 in 60-80 nm diameter has been deposited on carbon steel substrates, by cathodic electrophoretic deposition (EPD), in ethanol with poly(acrylic acid) (PAA) as charging agent, as a protective coating against corrosion for carbon steel (C.S.) in seawater environment. Potentiodynamic polarization measurements performed on the Al2O3 coated carbon steel coated by Al2O3in 3.5 % NaCl at temperature range 298-328 K and the result showed that using PAA charging agent lead to increase the corrosion resistance.
