Rapid growth of TiO2 nanotubes under the compact oxide layer: Evidence against the digging manner of dissolution reaction

open access: yesElectrochemistry Communications, 2019
The growth mechanism of porous anodic oxides still remains controversial. The field-assisted dissolution theory suggests that the growth of nanotubes is driven by a “top-down” digging manner.

Enhanced Corrosion Resistance of AZ91D Magnesium Alloy by Electric Field - Assisted Anodizing

open access: yesInternational Journal of Electrochemical Science, 2019
An external electric field was imposed on electrolytic cell in anodization of AZ91D magnesium alloy. The anodizing process became more stable with the assistance of the external electric field, and the obtained anodization film was smoother and compact ...

Fabrication of anti-aging TiO2 nanotubes on biomedical Ti alloys.

open access: yesPLoS ONE, 2014
The primary objective of this study was to fabricate a TiO2 nanotubular surface, which could maintain hydrophilicity over time (resist aging). In order to achieve non-aging hydrophilic surfaces, anodization and annealing conditions were optimized.

Study of the relationship between the crystal structure and micro-nano morphology of anodized stainless steels

open access: yesElectrochemistry Communications, 2019
In this work, we found that stainless steels with different crystal structures generated two new surface micro-nano morphologies after anodization. The surface morphologies were observed by field emission scanning electron microscopy (FE-SEM) and atomic ...

Influence of anodization time on the surface modifications on α-Fe2O3 photoanode upon anodization [PDF]

open access: yes, 2016
In searching for a suitable semiconductor material for hydrogen production via photoelectrochemical water splitting, α-Fe2O3 received significant attention as a promising photoanode due to its band gap (∼2.1 eV), good stability, low cost, and natural ...

Anodization of Aluminium using a fast two-step process

open access: yesProceedings of the Indian Academy of sciences. Chemical sciences, 2015
Ultra-fast two-step anodization method is developed for obtaining ordered nano-pores on aluminium (Al) foil. First anodization was carried out for 10 min, followed by 3 min of second anodization at high voltage (150 V) compared to previous reports of ...

Structural comparison of anodic nanoporous-titania fabricated from single-step and three-step of anodization using two paralleled-electrodes anodizing cell

open access: yesKKU Engineering Journal, 2016
Anodization of Ti sheet in the ethylene glycol electrolyte containing 0.38wt% NH4F with the addition of 1.79wt% H2O at room temperature was studied. Applied potential of 10-60 V and anodizing time of 1-3 h were conducted by single-step and three-step of ...
