Abstract

In the present work, we investigate wetting behavior and chemical composition of anodized titanium nanotubular surfaces for orthopedic implant research. The wetting behavior of the nanotubes by alternating UV irradiation and dark storage is reported. This study suggests that hydrophobicity due to aging in air can be restored by annealing, and release of residual fluorine was observed as a function of annealing time, which is important considering side effects of fluorosis. Fabrication of nanotubes on thermal plasma-sprayed implants and super-hydrophilic behavior of these nanotubular surfaces needed for enhanced bioactivity are demonstrated.
