摘要: Magnesium and its alloys have shown great potential as promising biodegradable implantation materials. However, rapid biodegradation has limited them to clinical applications. To overcome this disadvantage, a Ca/P coating was formed on AZ31B magnesium alloy by micro-arc oxidation (MAO) in three different electrolytes with without hydroxyapatite (HA). The surface properties were determined scanning electron microscope (SEM), X-ray diffraction (XRD), micro-hardness tester. Immersion tests, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) tests employed evaluate the corrosion behavior of MAO coatings simulated body fluid (SBF). results revealed that pore size would be changed electrolytes. show sample prepared electrolyte containing 4 g/L edetate calcium disodium (C10H12N2O8CaNa2 · 2H2O, EDTA-Ca), 1.5 g/L sodium hexametaphosphate (NaPO3)6, 2 g/L hydroxide (NaOH), 15 g/L metaaluminate (NaAlO2) HA smallest current density largest impedance.
