Electrochemical Evaluation of Corrosion Protection Properties of Protective Film by Zn/Sn Metal Spraying

This study is based on the electrochemical theory which aims to get the quantitative evaluation about corrosion protection of Zn-Sn metal spray method. The various existing corrosion resistance method and various mixture ratio of Zn-Sn metal spray method is applied with structural steel which is measured change of polarization resistance and corrosion potential. So corrosion protection of Zn-Sn metal spray method is tested. Consequently, coating side of Zn-Sn metal spray method was lower than electric potential of a structural steel adhesion side. So, Galvanic Protection of Zn-Sn metal spray found that structural steel advanced system. Accordingly, Zn-Sn metal spray method is expected as corrosion protection technology excellent in corrosion prevention of structural steel.��� ��������� ��������������������������������������������� ������������ ������������ ������������������ ��������� ������������������ ������ ������������ ��������� ���������(������������ : 12������������D02)��� ������������ ��������������� ������������ ��������������� ������������������ ������ ���������������������
