Abstract

TiO2 nanotubes were successfully synthesized by electrochemical method. A fluoride salt mixture was used as an electrolyte for synthesizing TiO2 nanotubes on titanium substrates. In this work, we have reported the synthesis procedure of TiO2 nanotubes and investigated the corrosion resistance of TiO2 nanotubes coated on the Ti substrate. FE-SEM was used to observe the morphology and determine the size of the TiO2 nanotubes. The phase formation and crystal quality of TiO2 nanotubes were studied by XRD measurements. One-microliter distilled water droplets were used to define the wettability of the TiO2 nanotube surfaces by measuring the contact angle. The corrosion resistance behavior of specimens was analyzed in the simulated body fluid solution (SBF) using potentiodynamic polarization tests for potential application as implants.
