Název v původním jazyce

TiO2 nanotubes grown on Ti and Ti6Al4V alloy spheres by bipolar anodization

Popis výsledku v původním jazyce

In this work, the anodization of spheres of Ti and Ti6Al4V alloy (TiAlV) in glycerol-based electrolytes usingbipolar electrochemistry is shown for the first time. TiO2 nanotube (TNT) layers were found over the entiresurface area of the Ti and TiAlV spheres using a square wave potential of ±60 V and ±65 V with 5.56 × 10− 4 Hz.The TNTs’ inner diameter on the extremities of the Ti spheres was ~63 nm and ~78 nm, for ±60 V and ±65 V,respectively. The inner diameter of the TNTs fabricated on the TiAlV spheres was ~36 nm and ~43 nm for ±60 Vand ±65 V, respectively. The effect of the alloying elements of the TiAlV spheres on the TNT layers was alsoinvestigated. To estimate the effective potential on the spheres contributing to the TNT layer formation, also theconventional anodization was performed on flat Ti and TiAlV foils for comparison. It was found that the effectivepotential reached on the extremities of the Ti and TiAlV spheres near the feeder electrodes was only 29 % and 16% of the applied potential, respectively.
