“…Even when phosphate ions were used by Matykina and co-workers, the same pattern was observed with a height of 0.32 µm at pH 4.2 and 1.75 µm at pH 4.6 [21]. Moreover, increasing the duration of the anodisation process increases the thickness too [8], [22], [23]. At the same time, the anodisation voltage has been shown to affect both the diameter and length of the nanotubes.…”

Anodization was performed in phosphate and fluoride containing electrolytes at different pH and sweep rates with the aim of analyzing the variation in current density during the process continuously. The effect of pH and sweep rate on the morphology of titanium dioxide (TiO2) nanotubes, grown on Ti-6Al-4V alloy, has been explicitly examined in this study. At the same time a microscopic analysis of the different stages of the formation of the nanotubes was performed. A new perspective to the growth mechanisms of the nanotubes was brought about in this study. The morphology of the nanotubes was closely related to the density of initial etching sites.

“…1,2 All these properties allow its application in implantology and orthopedic implants. Some authors [9][10][11][12] reported an increase in the adhesion and proliferation of cells in presence of nanotubular structures, but the effect of the diameter in the biological behavior is under discussion, some authors report the benefits of an internal diameter <30 nm in the biological performance, [12][13][14][15] on the other hand, some authors report an increase on the biological performance in nanotubular structures with an internal diameter >100 nm. This coating increases its chemical stability and delays the release of titanium ions.…”

Nanotubular structures were generated on the surface of titanium c.p. by anodization technique in an aqueous solution of acetic acid (14% v/v) with different sources of fluoride ion (HF, NaF, NH F). The aim of using these three different compounds is to study the effect of the counterion (H , Na and NH4+) on the morphology, wettability and surface free energy of the modified surface. Nanotubes were generated at 10 and 15 V for each anodizing solution. To further improve surface characteristics, the samples were heat-treated at 600°C for 4 h and at 560°C for 3 h. SEM images revealed the formation of nanotubes in all anodizing conditions, while their diameter increased proportionally to the electric potential. X-ray diffraction and micro-Raman spectroscopy results showed the presence of both anatase and rutile phases, with a higher content of rutile in the coatings obtained using NH F and an applied potential of 10 V. The heat-treatment significantly increased the wettability of the anodic coatings, especially for the coating obtained at 15 V with HF, which showed values < 7 degrees of contact angle. Besides, the nanotubes show a decrease in diameter due to the heat treatment, except for the nanotubes formed in NH F. Depending on their surface properties (e.g. low contact angle and high surface free energy), these coatings potentially have great potential in biomedical applications, sensors devices, and catalytic applications among others. © 2018 Wiley Periodicals, Inc.

Titanium oxide nanotube is gaining prominence in many applications like solar energy, sensors, catalyst and biomaterials. In this paper, we briefly review the electrochemical behavior of titanium oxide nanotube prepared by anodization in simulated body fluids. The electrochemical behavior of TiO 2 nanotube depends on its morphology and surface properties. When titanium oxide nanotube formed by anodization, these surface properties are depending strongly on two factors, the parameters of anodization process and the conditions of employed electrolyte. These factors must be chosen in correct manner to optimized titanium oxide nanotube with desired properties for specific application.
