Abstract :
Commercially titanium and its alloys are extensively applied in the study of biomedical implants, for example, dental and orthopaedic implants and the bio- compatibility of the titanium surface has been attributed to its firm oxide. In addition, surface alteration is used to regulate the properties of the titanium implant for specific medical applications, but there are still disadvantages of Ti and its alloys. Herein, we demonstrated the successful development of TiO&CaO&Sro ceramic coating on Ti alloy by electrodeposition to improve the corrosion resistance and biological properties. The surface characterization using FT-IR and XRD spectra confirmed the formation of TiO&CaO&SrO ceramic coating on Ti alloy. The results indicate that a hybrid combination of micro-arc oxidation and electrophoretic deposition can provide a phase-pure HA top layer and anticorrosive TiO2 interlayer, which should show good mechanical and biochemical stability in the corrosive environment of the human body.
