Characterization of CP-Ti Processed by Micro Arc Oxidation for Bone Implant Applications

Abstract:

Titanium and its alloys are potential candidates widely used to manufacture medical implants. In spite of possessing excellent properties suitable for a biomaterial, Ti suffers from lack of ability to bond with the local tissue termed as “bioactivity”. Several strategies have been adopted to increase the bioactivity of titanium for bone implant applications. Micro arc oxidation (MAO) is one of such promising surface treatments which produces an oxide layer on the surface of Ti which promote better tissue interactions at the surface Ti. Hence, in the present work, commercial pure Ti (CP-Ti) has been treated with MAO process and the produced surface was characterized to study the oxide layer developed on the Ti surface. X-Ray diffraction studies demonstrated the formation of TiO₂ layer on the surface of CP-Ti. Scanning electron microscope images and EDS analysis confirms the porosity in the produced oxide layer which is favorable towards better cell interactions. The presence of considerable amount of phosphorous in the oxide layer which is form the electrolyte used during MAO process was also observed. The preliminary findings demonstrate the simple and effective way to produce porous oxide layer on Ti for biomedical applications.
