Zn-Al 상온금속용사 피막의 전기화학적 방식성능 평가

Abstract

This study is based on the electrochemical theory which aims to get the quantitative evaluation about corrosion protection of Zn-Al metal spray method. The various existing corrosion resistance method and various mixture ratio of Zn-Al metal spray method is applied with structural steel which is measured change of polarization resistance and corrosion potential. So corrosion protection of Zn-Al metal spray method is tested. Consequently, coating side of Zn-Al metal spray method was lower than electric potential of a structural steel adhesion side. So, Galvanic Protection of Zn-Al metal spray found that structural steel advanced system. Accordingly, Zn-Al metal spray method is expected as corrosion protection technology excellent in corrosion prevention of structural steel.
