Formation of Titanium Dioxide Nanotube Arrays by Anodizing Ti6Al4V Alloy

Karakaya, İshak
Titanium dioxide thin films of nanoporous structures have gained great interest due to their large surface area and high reactivity properties in their applications. One of the methods used to form titanium dioxide nanostructures is anodizing the surface of titanium in F- ion containing electrolytes. Effects of HF concentration (0.1 to 0.5 wt.%), anodizing potential (10 to 30 V) and time (30 to 180 minutes) on the titanium dioxide nanotube formation were investigated by anodically oxidizing Ti6Al4V alloy in this study. Scanning electron microscopy (SEM) images were used to determine the influences of different experimental conditions. In addition, photovoltaic effects from a well-defined cell were used to infer comparative information on the total surface area of nanotubes.
