Fabrication of Tio2 crystalline coatings by combining Ti-6Al-4V anodic oxidation and heat treatments
(Hindawi Publishing Corporation, 2015-01)
The bio- and hemocompatibility of titanium alloys are due to the formation of a TiO2 layer. This natural oxide may have fissures which are detrimental to its properties. Anodic oxidation is used to obtain thicker films. ...
Advances on the synthesis of porous TiO2 coatings by anodic spark oxidation : photocatalytic reduction of Cr(VI)
(Elsevier, 2017-04-15)
Porous TiO2 coatings were obtained by anodic oxidation in spark discharge conditions, varying the range of current density (200–3000 A m−2) and the electrolyte concentration (H2SO4; 1 and 4 M). The samples were characterized ...
Corrosion resistance of titanium dioxide anodic coatings on Ti-6Al-4V
(Wiley, 2014-12)
The Ti–6Al–4V alloy is used for biomedical implants due to its corrosion resistance and biocompatibility, associated with the spontaneous formation of TiO2 oxide. However, the native film may be flawed and after some time ...
Influence of the electrolyte concentration on the smooth TiO2 anodic coatings on Ti-6Al-4V
(MDPI, 2017-03)
To obtain smooth TiO2 coatings for building a new design of Ti-6Al-4V heart valve, the anodic oxidation technique in pre-spark conditions was evaluated. TiO2 coating is necessary for its recognized biocompatibility and ...

Evaluation of the haemocompatibility of TiO2 coatings obtained by anodic oxidation of Ti-6Al-4V
(Elsevier, 2014-06)
The blood compatibility (haemocompatibility) is a requirement in materials used in prosthetic heart valves. No standardized methods are available to measure haemocompatibility in solid materials. However, a material could ...
Evaluation of the influence of texture and microstructure of titanium substrates on TiO2 anodic coatings at 60 V
(Elsevier, 2017-09-01)
The current paper analyzes the influence of texture and microstructure of Ti substrates on morphology and color of titanium dioxide coatings obtained by anodic oxidation. Substrates of Ti grade 2 and Ti grade 5 with different ...
Characteristics of hemocompatible TiO2 nano-films produced by the sol-gel and anodic oxidation techniques
(Springer, 2010-06)
Hemocompatible films can be obtained by different techniques which must produce a smooth surface and a desired combination of crystal structure including rutile and anatase structures. Two of the simplest techniques include ...
