Abstract:

Ti6Al4V alloy commonly used in human body for load bearing prosthesis was coated by micro arc oxidation (MAO) with magnesium rich TiO₂ oxide. Since the presence of magnesium in bone tissues is known to promote bone formation and proliferation in physiological environment, its integration with TiO₂ on implant surface could bring about a bioactivity for a fast bone formation and proliferation. The formation of a composite layer consisting of Mg integrated TiO₂ by MAO process was carried out in an electrolyte with different magnesium content. The characterization studies of these coatings were performed by using X-ray diffractometry (XRD), scanning electron microscopy (SEM) coupled with EDS analysis and XP2 surface profilometry.
