摘要: Abstract Magnesium alloys are newly promising biomaterials with potential application of human bone replacement. However, there is a drawback due to their high corrosion rates. In this study, AZ31 magnesium were coated using microarc oxidation (MAO) process. Two durations, 1 minute and 5 minutes, used. The samples immersed in the simulated body fluid (SBF) for up seven days. Then electrochemical behaviors two comparatively investigated. Potentiodynamic polarization impedance spectroscopy (EIS) experiments results show that 5-minute MAO sample had better resistance than 1-minute sample. study shows processing parameters, e.g., time, can be used design an optimized MAO-coated alloy controlled
