Fueled by demands for reductions of carbon emissions and improving the recyclability of automobiles and other transport vehicles, manufacturers have looked to magnesium (Mg) alloys as a possible replacement for heavier metallic counterparts and non-recyclable materials. Use of alternative energy sources such as hybrid and battery or fuel cell powered cars alleviates some of the environmental impact of fossil fuels. However, these technologies continue to require lighter materials in order for vehicles to remain energy efficient. The reduction of CO2 emissions due to use of Mg alloys in automotive applications is significant.1 The advantages of Mg are counterbalanced by its high electrochemical activity,2 creating a large driving force and propensity for corrosion. It is known that MgO and Mg(OH)2 scales formed during corrosion or oxidation of Mg are porous and easily dissolved in water,3thus becoming nonprotective. Gaining a fundamental understanding of the active corrosion...
