Title: To study the corrosion behavior of friction stir processed magnesium alloy AZ91
Abstract: The main aim of the study is to investigate the effect of the corrosion behaviour of Friction Stir Processed (FSPed) AZ91 magnesium alloy. The corrosion testing was performed by immersing the FSPed samples in 3.5 % (by weight) sodium chloride (NaCl) solution. It is originally proved that the corrosion rate of AZ91 FSPed samples decreased significantly with a square pin profile as compared to the round pin profile. It is attributed that the pulsation effect of the flat-faced tool helped to improve the flow of material. Also, Friction Stir Processing (FSP) modified the surface morphology and uniformly distributed the β-Mg17Al12 phase particles that helped in improving the corrosion rate of AZ91 alloy.
