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

International 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 ...

First-Step Anodization of Commercial Aluminium in Oxalic Acid: Role of Anodization Voltage in Tailoring the Structural Features of Porous Alumina Film and Aluminium Substrate

International Journal of Electrochemical Science, 2019
Commercially pure Al specimens were anodized in 0.3 M oxalic acid at 0 °C for 15 min using five different anodization voltages in the range 10 – 50 V. Current versus time transient plots for each anodization voltage were recorded via computer interfaced ...

Porous silicon solar cells [PDF]

, 2015
We developed a new process for the fabrication of crystalline solar cell, based on an ultrathin silicon membrane, taking advantage of porous silicon technology. The suggested architecture allows the costs reduction of silicon based solar cell reusing the

Investigation on some factors affecting crack formation in high resistance aluminum alloys [PDF]

, 2017
Aluminum alloys having good mechanical properties are Al-Zn-Mg alloys (7xxx) and Al-Cu-Li alloys (Weldalite®). These alloys may be subjected to stress corrosion cracking.

Engineering of Hybrid Nanoporous Anodic Alumina Photonic Crystals by Heterogeneous Pulse Anodization

Scientific Reports, 2018
In this study, we present an advanced nanofabrication approach, so-called ‘heterogeneous pulse anodization’ (HPA), in which galvanostatic stepwise and apodized sinusoidal pulse anodizations are combined in a single process.

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

PLoS 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.

Stainless steel made to rust: a robust water-splitting catalyst with benchmark characteristics [PDF]

, 2015
The oxygen evolution reaction (OER) is known as the efficiency-limiting step for the electrochemical cleavage of water mainly due to the large overpotentials commonly used materials on the anode side cause.

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

Electrochemistry 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 ...
