The evolution of the electrical discharges parameters during spark anodization of metallic Zr under galvanostatic regime have been investigated by image analysis in phosphoric and oxalic acid electrolytes. The experiments ...

The aim of this paper is to investigate changes in morphology and microstructure of TiO2 films, prepared by sparking anodization of Ti in a H3PO4 solution, by applying different formation charges. We show that although ...

A myriad of titanium (Ti) surface modifications has been proposed to hasten the osseointegration. In this context, the aim of this study was to perform histomorphometric, cellular, and molecular analyses of the bone tissue ...

The results of an extensive operation of a vacuum spark plasma using Titanium electrodes in a 120-ns 150-kA discharge are presented. The hot spots are found to form with a regular spacing in a zippering Z-pinch plasma, ...

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 ...

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 ...

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 ...
