Abstract

Silicone-modified epoxy coatings were prepared and treated under different plasma atmospheres in order to enhance their anticorrosion ability. The corrosion current density, corrosion potential and impedance of the modified coatings were measured by an electrochemical workstation. The results showed that the corrosion resistances of silicone-modified epoxy coatings were highly improved by surface-wave plasma treatment. Compared with the original coating, the corrosion current density of these coatings modified by plasma decreased from 0.5976 μA/cm² to the minimum of 0.0058 μA/cm² and the impedance increased from 1.925×10³ Ω·cm² to the maximum of 2.938×10⁶ Ω·cm², in which Ar plasma showed the best significant effect.
