Sacrificial Protection

Corrosion protection by anodization and conversion treatment in phosphate solution was studied by microstructural and electrochemical analysis. Both the anodized and the conversion-treated layers showed sacrificial protection in a solution of sodium chloride. The corrosion current or the dissolving rate of the anodized layer was smaller than that of the conversion-treated surface. The modified layers had another mode of protection to form protective films on magnesium substrate where the original modified layers were mechanically lost. Since the state of magnesium in the anodized layer is close to magnesium oxide, phosphorus in the layer is considered to have an important role in these properties concerning the above corrosion protection.

Structure Property Relationship

Magnesium alloys offer high potential for lightweight constructions, e.g. in automotive applications. However, their application range is limited due to their low corrosion resistance. In the present study, the influence of corrosion on the microstructure and the depending mechanical properties under cyclic loading were characterized for the creep-resistant DieMag422 (Mg4Al2Ba-2Ca) and AE42 magnesium alloys. In this context, fatigue properties in distilled water and sodium chloride solutions were assessed in constant amplitude tests. The results were correlated with corrosion properties of the alloys, which were evaluated by immersion tests. Corrosion-and deformation-induced microstructural changes were observed by light and scanning electron microscopy (SEM), yielding a structure-property-relationship for a comprehensive understanding of mechanical and corrosive deterioration mechanisms.
