摘要：

We demonstrate an approach for Bioglass/TiO2 nanocomposites coatings onto the TiO2 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/TiO2 composites are prepared by changing the TiO2 concentration. The coating is performed by electrophoretic deposition technique, and it shows less concentration of TiO2 gives higher adhesion to the substrates. The in vitro electrochemical corrosion and immersion studies confirm that the lower concentrations of TiO2 containing Bioglass/TiO2 composites coated sample possesses higher corrosion resistance and bio-mineralization that is highly suitable for bone osseointegration applications.
