Surface modification by friction stir processing (FSP) was performed to improve the corrosion resistance of the AZ31 magnesium alloy. The corrosion behavior was characterized by in-situ monitoring of acoustic emission (AE) signals during electrochemical polarization tests. The corrosion potential increased and the corrosion current density decreased for the FSPed specimen because of the formation of a passivation layer by dynamicallyrecrystallized smaller grains. AE parameters, including number of AE counts and count rate, were analyzed in accordance with the corrosion time and mechanism. The AE-features were correlated with microstructural observations, simultaneous video monitoring and electrochemical polarization plots. The AE methodology for corrosion monitoring was validated based on the quantitative correlation between AE and corrosion parameters.
