Physical Characterization of Cathodically-Activated Corrosion Filaments on Magnesium Alloy AZ31B

In this study, the filiform-like corrosion behavior of Mg alloy AZ31B was characterized using analytical microanalysis. Recent electrochemical measurements have shown that the corrosion filaments on AZ31B support enhanced cathodic reaction kinetics, but there has been little strong physical evidence published to explain this behavior. Hence, the specific aim of the investigation was to contribute to the understanding of the physical origin of...
