摘要
With scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS) technique, properties of oxide coatings produced at different voltage on AZ91D Mg alloy substrates by micro - arc oxidation technique have been investigated. Three types of oxide coatings, passive film, micro - spark oxide coating and spark oxide coating were formed corresponding to different range of voltages. The results showed that micro - spark oxide coating exhibited the best performance of compact, homogeneous and with high resistance, comparing with other two types of oxide coatings, due to its high effective thickness.
