Anodic Fabrication of Ti-Nb-Zr-O Nanotube Arrays

الملخص EN

Highly ordered Ti-Nb-Zr-O nanotube arrays were fabricated through pulse anodic oxidation of Ti-Nb-Zr alloy in 1 M NaH2PO4 containing 0.5 wt% HF electrolytes.

The effect of anodization parameters and Zr content on the microstructure and composition of Ti-Nb-Zr-O nanotubes was investigated using a scanning electron microscope equipped with energy dispersive X-ray analysis.

It was found that length of the Ti-Nb-Zr-O nanotubes increased with increase of Zr contents.

The diameter and the length of Ti-Nb-Zr-O nanotubes could be controlled by pulse voltage.

XRD analysis of Ti-Nb-Zr-O samples annealed at 500°C in air indicated that the (101) diffraction peaks shifted from 25.78° to 25.05° for annealed Ti-Nb-Zr-O samples with different Zr contents because of larger lattice parameter of Ti-Nb-Zr-O compared to that of undoped TiO2.
