The Comparision of Corrosion Resistance of Amorphous and Nanocrystalline Fe-based Alloys in NaOH Solutions

The electrochemical corrosion behavior of Fe78Si13B9 amorphous and Fe73.5Si13.5B9Nb3Cu1 nanocrystallized alloys have been performed by linear polarization method in different concentrations of NaOH solutions.The results showed that both amorphous Fe78Si13B9 alloy and nanocrystallized Fe73.5Si13.5B9Nb3Cu1 alloy had similar change rules with variety of NaOH solution concentration,and nanocrystalline alloys have a higher corrosion resistance than amorphous alloys in NaOH solutions.
