Abstract

This work aims to clarify the influence of texture on the corrosion behavior of an as-extruded Mg–8Al-0.5In alloy sheet. The weight loss, hydrogen evolution and electrochemical results show that the sample with strong basal texture has the best corrosion resistance. The morphology examinations show the corrosion product film is thinner and more uniform with less cracks for the sample with (0001) plane. The inhomogeneity of corrosion product in samples with (10-10) and (-12-10) planes is the main cause of poor corrosion performance. The findings of this study confirm the corrosion resistance of Mg alloy could be regulated by controlling texture.
