영문 초록

In recent years it has been observed that coated steel structures are rapidly deteriorated than designed life time due to acid rain caused by air pollution etc.. Therefore improvement of corrosion resistance of anti-corrosive paint is very important in terms of safety and economic point of view. In this study corrosion resistance for five kinds of anti-corrosive paints including Acryl, Fluorine and Epoxy resin series were investigated with electrochemical methods such as corrosion potential, polarization curves, impedance and cyclic voltammogram measurements etc.. There were some good relationships between all of them such as corrosion current density, impedance and polarization resistance on the cyclic voltammogram to evaluate corrosion resistance, for example, corrosion current density was decreased with increasing of impedance and polarization resistance on the cyclic voltammogram. Although a corrosion potential of F101 of Fuorine resin series shifted to negative value than other anti-corrosive paints, its corrosion resistance, indicating on the cathodic and anodic polarization curves, impedance and cyclic voltammogram, was the most superior to other paints, whereas A100 containing Arcyl resin showed a relatively poor corrosion resistance compared to other paints.
