Coating residual stress effects on fatigue performance of 7050-T7451 aluminum alloy
(Elsevier B.V., 2007-10-15)
The tendency of the aircraft industry is to enhance customer value by improving performance and reducing environmental impact. In view of availability, aluminum alloys have a historically tendency to faster insertion due ...
Electrochemical treatment of tannery wastewater using DSA (R) electrodes
(ELSEVIER SCIENCE BV, 2008)
In this work we studied the electrochemical treatment of a tannery wastewater using dimensionally stable anodes (DSA (R)) containing tin, iridium, ruthenium, and titanium. The electrodes were prepared by thermal decomposition ...
Electrochemical oxidation of synthetic tannery wastewater in chloride-free aqueous media
(ELSEVIER SCIENCE BV, 2010)
The electrochemical treatment of a synthetic tannery wastewater, prepared with several compounds used by finishing tanneries, was studied in chloride-free media. Boron-doped diamond (Si/BDD), antimony-doped tin dioxide ...
Advances on the synthesis of porous TiO2 coatings by anodic spark oxidation: photocatalytic reduction of Cr(VI)
(Elsevier Science Sa, 2017-04)
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 ...

A hybrid photoelectrocatalytic/photoelectro-Fenton treatment of Indigo Carmine in acidic aqueous solution using TiO2 nanotube arrays as photoanode
(2019-08-15)
This article reports the synthesis of TiO2 nanotube arrays (TiO2 NTs), grown by Ti anodization, and their use as photoanode in a hybrid photelectrocatalytic (PEC)/photoelectro-Fenton (PEF) treatment of Indigo Carmine ...
A first insight on the bio-functionalization mechanisms of TiO2 nanotubes with calcium, phosphorous and zinc by reverse polarization anodization
(2017-09-15)
The decoration of titanium (Ti) implant surfaces with TiO2 nanotubes has emerged as a promising strategy to improve osseointegration and avoid infection. Nevertheless, it has been reported that nanotubular films are prone ...
Anodização para obtenção de membranas cerâmicas
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2007-12-17)
This a study on the achievement of alumina membranes by the method of anodizing. From this method got up a layer of aluminum oxide on the anodic metal, who presented the basic
properties necessary for the application as a ...
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. ...
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 ...
