To evaluate anti-corrosion performance of high-frequency arc metal spray film in accordance with metal type and epoxy sealing coat application status, electrochemical impedance spectroscopy(EIS) method was conducted in this study. As a result, in case of applying Al-Mg alloy metal spray film, it showed the best polarization resistance. In case of applying epoxy sealing coat, it showed increased polarization resistance of arc metal spray film. Through this experiment, it is judged that Al-Mg alloy arc metal spray film with epoxy sealing coat can increase the biggest anti-corrosion performance of high-frequency arc metal spray film on steel.
