Abstract
Manganese is a common addition to magnesium (Mg) alloys. In aluminium (Al) containing Mg alloys, the formation of Al 8(Mn,Fe) 5 phase improves the corrosion resistance by removing elemental Fe particles from the Mg. The influence of Mn on the corrosion of Mg alloys in the absence of Al is not well documented. As such, in this study, several commercially pure Mg samples were compared to alloys with varying additions of Mn and Fe. The corrosion rate of these samples was examined via electrochemical and immersion tests. It was seen that samples with Mn additions exhibited an increased Fe impurity tolerance level. This indicates that the Mn addition was able to moderate the effect of the Fe impurity on the corrosion of the Mg alloy even without Al being present.
