Electrophoretic Deposition of Titania Based Coating on Ti-6Al-4V Implants for Orthopaedic Applications

Abstract

Titanium dioxide (TiO2) is a propitious biomaterial for orthopaedic implants ascribed to its, biocommpatibility, inertness and non-toxic nature. Graphene oxide (GO) incorporated rutile Titanium dioxide has the combined properties of both, with enhanced performance and functionality in biomedical field. It comports as an ideal coating for orthopaedic implant by improving the mechanical strength, thermal stability and antimicrobial properties. GO is synthesized by Modified Hummer’s method. The GO incorporated with TiO2 is fabricated by sol-gel method. The preliminary studies of synthesized composite powder were examined with XRD, FTIR, UV-Vis Spectroscopy, Photoluminescence, Scanning Electron Microscopy, and Raman spectroscopy. The synthesized GO doped TiO2 at optimized weight percentage was coated on titanium alloy implant using Electrophoretic deposition technique. Optimized coating is selected by varying voltage parameters with fixed time duration. Uniform and crack free coatings are observed at 80V at 180 seconds.
