Stacked Bioglass/TiO2 nanocoatings on titanium substrate for enhanced osseointegration and its electrochemical corrosion studies

Abstract We demonstrate an approach for Bioglass/TiO 2 nanocomposites coatings onto the TiO 2 nano-surfaces formed by etching of CP-Ti. The coated surface is further covered with Bioglass fibres to enhance the rate of apatite formation. Different concentrations of Bioglass/TiO 2 composites are prepared by changing the TiO 2 concentration. The coating is performed by electrophoretic deposition technique, and it shows less concentration of TiO 2 gives higher adhesion to the substrates. The in vitro electrochemical corrosion and immersion studies confirm that the lower concentrations of TiO 2 containing Bioglass/TiO 2 composites coated sample possesses higher corrosion resistance and bio-mineralization that is highly suitable for bone osseointegration applications.
