용사금속 종류에 따른 산성용액에서의 전기화학적 방식성능 평가

Abstract

Due to the oxidizing power of ozone used in the advanced water treatment facilities There are problems in the concrete structure of the advanced water treatment plant such as deterioration of waterproofing, anti-corrosion materials and concrete In this study, metal spraying method was applied to the advanced water treatment facilities to improve durability. In an acidic solution of pH 3 similar to the pH concentration that occurs during actual ozone treatment, The performance of the electrochemical anti-corrosion according to the type of the sprayed metal was evaluated. As a result, Ti showed the polarization resistance of 409.46 k ∙ Ω · cm 2, indicating the best performance of electrochemical anti-corrosion
