Original Abstract

Accurate assessment of magnesium degradation is crucial for the development of safe medical devices. X-ray computed microtomography is one of the methods that are recently used to evaluate the corrosion of magnesium. This work validates the potential of this method to discern the different corrosion rates of different surfaces of a magnesium coupon, representing a real advantage of this technique over other methodologies that only evaluate the overall corrosion behaviour. The results also show that magnesium corrodes faster in zones with high twin density and that its corrosion product formation varies in different simulated physiological fluids.
