Abstract

The role of precipitated Mg-containing corrosion product in the anodic behavior of the steel in aqueous corrosion was ascertained to analyze the corrosion protection mechanism at steel substrate of the Zn-Al-Mg coated steel. For the Zn-Al-Mg coating, the corrosion products that formed during the immersion test passivated the steel in the deaerated solution at pH 8.2. EDS analysis revealed that Mg-species remained on the steel after polarization. However, the concentration of Mg decreased after polarization. The results indicated that the alkalization and barrier effect by the Mg-containing corrosion products passivated the steel substrate, preventing red rust generation at the cut-edge.
