In recent years, smart implants take the most attention in the field of bone manufacturing. Our study seeks to develop the biodegradability of Mg alloys to use orthopedic implants for the biomedical applications to avoid post removal of the implant. Mg and Zn are very important to human body and have no toxicity. Mg - 6% wt Zn biodegradability is studied in simulated body fluid for two and four weeks. Four electro-deposition bathes are used to deposit a coat on the substrate to improve the corrosion resistance of this alloy in the media of simulated body fluid. The following analyses were studied to emphasize the research aim. Scanning electron microscope (SEM), Energy dispersive X-Ray (EDX) analysis shows the surface morphology and the elements of the coat phases components. The results also confirmed by X-Ray diffraction Pattern (XRD) that show the phases that confirmed the formation of hydroxyapatite HA phase, Fourier-Transform Infrared Spectroscopy (FTIR) to investigate the functional groups of the phases coats that confirm the formation of hydroxyapatite and the electrochemical measurements that investigate the improvement of corrosion resistance. The results indicated that the fourth bath gives the best coat and four weeks immersion gives more corrosion resistance than two weeks.
