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 ...
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 ...

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 ...
Effects of negatively and positively charged Ti metal surfaces on ceramic coating adhesion and cell response
(2017-02-01)
Abstract: This manuscript reports an evaluation of the effects of simple chemical-heat treatments on the deposition of different ceramic coatings, i.e., TiO2, CaTiO3 and CaP, on commercially pure titanium (cp-Ti) and Ti6Al4V ...
Enhanced photochromic response of ormosil-phosphotungstate nanocomposite coatings doped with TiO2 nanoparticles
(Springer, 2015-11-01)
Photochromic ormosil-phosphotungstate hybrid materials were prepared by immobilizing phosphotungstic acid, H3PW12O40, (HPW) in hybrid organic-inorganic ormosil matrices via sol-gel route, and the effect of addition of TiO2 ...
