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. ...

TiO2 Coating of High Surface Area Silica Gel by Chemical Vapor Deposition of TiCl4 in a Fluidized-Bed Reactor
(American Scientific Publishers, 2011-09)
TiO2 was deposited on high surface area porous silica gel (400 m2g−1) in a fluidized bed reactor. Chemical vapor deposition was employed for the coating under vacuum conditions with TiCl4 as precursor. Nitrogen physisorption, ...
Antibacterial photocatalytic activity of different crystalline TiO2 phases in oral multispecies biofilm
(2018-07-01)
Objective: Titanium dioxide (TiO2) incorporation in biomaterials is a promising technology due to its photocatalytic and antibacterial activities. However, the antibacterial potential of different TiO2 crystalline structures ...
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 ...
Deposition of TiO2 thin films by dip-coating technique from a two-phase solution method and application to photocatalysis
(2021-01-01)
A derivation of the sol-gel-dip-coating deposition technique is proposed, where the precursor solution exhibits two separated liquid phases, reaching an equilibrium state in a heterogeneous solution. Structural, optical ...

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 ...
TiO2 Coatings in Alkaline Electrolytes Using Anodic Oxidation Technique
(Elsevier Science, 2014-06)
For the construction of a new design of mechanical heart valve a Ti-6Al-4V alloy was selected and coated with TiO2 due to it corrosion resistance and biocompatibility. A required feature on surfaces in contact with blood ...
Determinación por reflectometría de rayos X del espesor de recubrimientos de TiO2 obtenidos por oxidación anódicaDetermination using X-ray reflectometry of the TiO2 coating’s thickness obtained by anodic oxidation
(Asociación Física Argentina, 2010-12)
El proceso electroquímico de oxidación anódica permite obtener recubrimientos de TiO2 de mayor espesor y densidad que el que crece naturalmente sobre aleaciones de titanio, el cual frecuentemente no supera los 10nm de ...
