a b s t r a c tIn order to improve its tribocorrosion resistance, nanotubular structures were produced on Ti6Al4V surfaces by anodic treatment in a mixture of 1 M H 2 SO 4 and 0.08 M HF electrolyte. Tribocorrosion tests were performed in a phosphate-buffered saline solution (PBS) against an alumina ball under 50 mN. Results showed that nanostructured surfaces exhibited significantly lower tendency to corrosion due to the protecting effect given by the well-adherent TiO 2 nanotubular layer.

“…Unfortunately, these alloys exhibit often a fail after long-term use in the human body due to an incomplete osseo-integration [9] and ions release. Therefore, to overcome these problems, the modification of the smooth surface of Ti-alloys have received considerable attention in order to improve the biocompatibility of titanium and to enhance the bone growth, this modification was carried out by various coating methods such as: thermal oxidation [10,11], electrochemical anodization [12][13][14][15], hydroxyapatite coating [16][17][18] and alkaline treatment with NaOH [19,20], etc.…”

“…The elements of the EEC proposed are: R1 for solution resistance, R2 for charge transfer resistance of the passive film in the case of the Ti6Al4V alloy and charge transfer resistance of the nanoporous layers for the as-anodized and the annealed samples, CPE2 for constant phase element of the double layer, CPE3 for the inner compact oxide for the as-anodized and the annealed samples, R3 for charge transfer resistance, W4 related to the mass transport limitation by diffusion [15]. J. Grotberg, et al have reported similar equivalent electrical circuits when they perform the EIS on the Ti6Al4V, as-anodized and annealed nanotubes under OCP conditions in solution containing proteins [15]. Table 2 recapitulates the obtained values of each element as calculated by EC-Lab express software from the fit of the experimental data.…”

Nanostructured Titania layers formed on the surface of titanium and titanium alloys by anodic oxidation play an important role in the enhancement of their biocompatibility and osseointegration in the human body. For this purpose, we aimed to study in the current work the structural and electrochemical properties of amorphous and crystallized nanostructured TiO2 thin films elaborated on Ti6Al4V substrate by electrochemical anodization in fluoride ions (F -) containing electrolyte at 10 V during 15 min and heat treated in air at 550 °C for 2 h. The morphology, chemical composition and phase composition of synthesized layers were investigated using field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD). The corrosion resistance improvement of both as-anodized and annealed titania layers was evaluated in 0.9 wt. % NaCl solution with pH  6.4 at room temperature by means of open circuit potential (Eoc),potentiodynamic polarization (PDYN) and electrochemical impedance spectroscopy (EIS).

“…Very interestingly, in particular, TiO 2 NTs have also shown potential to prevent long-term implant failure due to biocorrosion. 23 In general, both the nanotubular surfaces display a fast and effective passivation behavior, which may be related to the properties of the barrier layer formed at TN interfaces during the anodization process. 24 The same trend was observed by Grotberg et al 23 for NTs grown from Ti6Al4V substrates.…”

Background Two frequent problems associated with titanium (Ti) surfaces of bone/dental implants are their corrosion and lack of native tissue integration. Methods Here, we present an anodization-hydrothermal method for coating Ti surfaces with a layer of silicon (Si)- and strontium (Sr)-loaded titania nanotubes (TNs). The Ti surfaces coated with such a layer (Si–Sr-TNs) were characterized with different techniques. Results The results indicate that the Si 4+ and Sr 2+ ions were evenly incorporated into the TNs and that the Si–Sr-TN layer provides good protection against corrosive media like simulated body fluid. The excellent cytocompatibility of the coating was confirmed in vitro by the significant growth and differentiation of MC3T3-E1 osteoblastic cells. Conclusion Being easily and economically fabricated, the Si–Sr-TN surfaces may find their niche in clinical applications, thanks to their excellent biological activity and corrosion resistance.
