Abstract:

Magnesium (Mg) and its alloys have been widely under investigation for their possible use as bone implant materials due to their good biocompatibility and optimum mechanical properties. However, the high corrosion rate of Magnesium (Mg) alloys in chloride-containing environment including human body fluid would make the Mg-based implants fail before bone tissues recovery, thus a sustainable surface treatment is mandatory before promoting the widespread use in biomedical implants. In this study, Plasma Electrolytic Oxidation Coating has been formed on Magnesium (Mg) alloy. Several Zn-based precursors such as Zinc hydroxide and Zinc phosphate were under various conditions, keeping the sodium phosphate electrolyte as the primary component to prepare PEO coatings on the substrates. Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) were used for the microstructure and phase analysis of the produced coatings. Furthermore, corrosion analysis of the coating was analyzed in simulated body fluid at normal and body pyrexia conditions. Significant effects were found on the biocompatibility, biodegradability, and Osseo-integration of the coated Mg alloy. Keywords: AZ31, Orthopedic implant, Simulate body fluid, Corrosion, SEM
