Abrupt corrosion, initiated by Fe impurity, was observed in the latter stage of experimentation in the form of preferred crystallographic pitting (PCP) propagating along the (0001) basal plane in the grain. Herein, we report the mechanism behind PCP corrosion of Mg and evaluate potential solutions to suppress PCP corrosion. In particular, the addition of Mn inhibits PCP initiation by converting Fe impurities to Fe-Mn compounds, while refining the grain size by extrusion reduces PCP propagation. (C) 2012 Elsevier Ltd.
