금속 종류에 따른 아크 금속용사피막의 임피던스 특성에 관한 실험적 연구

Abstract

Arc Thermal Metal Spraying Method (ATMSM) provides proven long term protective coating systems using zinc, aluminum and their alloys for steel structure in a marine environment than two conventional anti-corrosion method; heavy duty coating and hot dip galvanizing. This paper focused on studying the effect of spraying metal type on impedance properties of Arc Thermal Metal Spraying (ATMS) film. The results showed that the impedance property of ATMS film significantly varied depending on whether the metal type applied pertains to Zn or Al series. Also, the reaction system between the interface of ATMS film and electrolyte was analysed by interpreting its equivalent circuit. Consequently, the representative equivalent circuits were presented as models to be applied on ATMS film.
