This book was released on 2013 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: All treatments showed the presence of [TiO2] nanotubes. Furthermore, the [TiO2] nanotube diameter and coating thickness (or tube length) are relatively homogeneous across each sample surface. Finally, nanotube length increased with increasing anodization time for all electrolyte compositions. Results showed that processing conditions during anodization play an important role in the adhesion strength at the [TiO2] nanotube to Ti interface. The anodization time was found to directly correlate with the coating thickness. In general, nanotube coating adhesion strength increased with increasing anodization time. Also, for the same electrolyte composition, adhesion strength increased with increasing coating thickness. However, adhesion strength was not controlled solely by coating thickness, as it was observed that the adhesion strength varied between samples processed with different electrolyte composition but with similar thickness. The mechanism for dependence of adhesion strength on coating thickness and anodization time is likely related to stress development within the nanotube coating as well as oxide stoichiometry at the [TiO2/Ti] interface.
