Fabrication of TiO2 nanotubes with effect of water and in‐situ condition for biomedical application

Abstract Synthesis of TiO 2 nanotubes on titanium alloys for environmental and energy applications are highly encouraged by medical industries. Formation of nanotubes on titanium material delivers superior properties in the view of phase transformation, surface morphological, nanomechanical properties, and corrosion resistances. In this research work, synthesis of TiO 2 nanotubes under 8 and 12 Vol. % of water content with in‐situ voltage condition. The fabricated nanotubes surface morphology was analyzed with the use of HR‐Sem. The formation of nanotubes surface has been identified with composite faces of smooth and rough (length of 1.6 and 1.8 μm) by the effect of water content and voltage variations. The nanomechanical properties were analyzed with nanoindentation Pmax received as max of 265 and min of 248 μN. Nanotubes strength depends on the nanotubes length. Potentiodynamic polarization analysis indicated that combination of smooth and rough surfaces was highly encouraging the corrosion resistances.
