|Abstract||In this study, a bioactive Sr containing Ca-P (Sr-CaP MAO) coating was obtained through the combination of preceding chemical deposition and micro-arc oxidation treatments for the purpose of modifying the surface of the magnesium to promote the bioactivity and to reduce the degradation rate. The microstructure, element and phase composition of the coating were investigated by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). Electrochemical and immersion tests were conducted to evaluate the degradation behavior of the Sr-CaP MAO coating in a Hank's solution. The results showed that Sr was successfully incorporated into the Pre-CaP coating by the two-step procedure. The in vitro degradation evaluation indicated that the Sr-CaP MAO coating could significantly reduce the corrosion rate of pure magnesium and show better biomineralization property.
