HAp/TiO2 Composite Coatings and its Effective Use in Biomedical Applications

Abstract

Hydroxyapatite and Titania being able to exhibit a plethora of distinct applications related to bone-tissue regeneration and orthopaedic implantations, we consider them as our essential materials under concern. The present investigation deals with HAp/TiO₂ composites and its preliminary characterizations based on the results from XRD, FTIR, SEM and further extending the studies to electrophoretic deposition of the composite coating. The results from XRD and FTIR gave a confirmation on the phase transformation studies of TiO₂ from anatase to rutile. HAp inherently exhibits adequate biocompatibility and osteoregenerative applications and hence used extensively for coatings over implants. Composite was made using HAp and TiO₂ to provide a better preferable coating for the orthopaedic implant through electrophoretic deposition technique by varying voltage parameter. From our current study with preliminary outcomes, we confirmed that the HAp/TiO₂ composite is a promising coating and could be opted for biomedical applications.
