Fabrication of Ni-Ti-O nanotube arrays by anodization of NiTi alloy and their potential applications
Nickel-titanium-oxide (Ni-Ti-O) nanotube arrays (NTAs) prepared on nearly equiatomic NiTi alloy shall have broad application potential such as for energy storage and biomedicine, but their precise structure control is a great challenge because of the high content of alloying element of Ni, a non-valve metal that cannot form a compact electronic insulating passive layer when anodized. In the pre...
متن کاملControlled Fabrication of Nanoporous Oxide Layers on Zircaloy by Anodization
We have presented a mechanism to explain why the resulting oxide morphology becomes a porous or a tubular nanostructure when a zircaloy is electrochemically anodized. A porous zirconium oxide nanostructure is always formed at an initial anodization stage, but the degree of interpore dissolution determines whether the final morphology is nanoporous or nanotubular. The interpore dissolution rate ...
متن کاملFabrication of alumina films with laminated structures by ac anodization
Anodization techniques by alternating current (ac) are introduced in this review. By using ac anodization, laminated alumina films are fabricated. Different types of alumina films consisting of 50-200 nm layers were obtained by varying both the ac power supply and the electrolyte. The total film thickness increased with an increase in the total charge transferred. The thickness of the individua...
متن کاملInvestigation on the ordering of titanium oxide nanotubes fabricated by anodization on different substrate surface morphologies
In this study, titanium oxide nanotubes anodized on threedifferent surface morphologies of titanium foils, were investigated. AFM imagesis used to show different surface roughness of these foils. Nanotubes wereanodized on titanium foils with 1) no polishing process (A sample), 2)electropolishing process (B sample) and 3) electropolishing process in ethanolicelectrolyte (C sample). To study the ...
متن کاملFabrication of Iron (iii) Oxide Nanostructures by Potentiostatic Anodization
Iron (III) oxide (Fe2O3) is an excellent material for absorbing visible light from the solar spectrum because of its suitable band gap. However, due to low mobility and high bulk carrier recombination, the photoconversion efficiency of iron (III) oxide has been proven to be very poor. Fabrication of nanostructured iron oxide can potentially compensate for the material’s poor properties. In this...
