摘要

Nowadays, Mg based metals attract much attention because of their biodegradability and bioactivity. However, over fast degradation rate still restrict their widely medical application. Therefore, surface protection treatment is necessary to control the degradation rate. In this study, a ceramic coating was successfully fabricated on pure magnesium by Micro-arc oxidation (MAO) method. The surface quality was dramatically influenced by deposition parameters such as voltage and frequency. The composition of the sample was characterized by X-ray diffraction (XRD) and the surface morphology was characterized by scanning electron microscope (SEM) equipped with energy dispersive spectroscopy (EDS). The degradation behavior of MAO coated Mg was investigated. It is expected that pure Mg with MAO coating can be used for the orthopedic application especially as bone screw.
