| Research Abstract |
This study focused on cut-edge corrosion mechanism of galvanized steels. In order to investigate anodic and cathodic reactions on steels with Zn corrosion products formed in 1 M NaCl and 1 M MgCl2, electrochemical microcell technique was employed. The morphology and compositions of Zn corrosion products formed on the steels depended on solution compositions and the distance from zinc coating layer. In addition, cathodic reaction was suppressed to some extent by deposition of the corrosion products. On the other hand, anodic reaction was suppressed on steel significantly by precipitation of the corrosion products containing Mg.
