Classic and local analysis of corrosion behaviour of graphite and stainless steels in polluted phosphoric acid [PDF]

open access: yes, 2006
In phosphoric acid solution (40% H3PO4), the corrosion behaviour of graphite and stainless steels was studied by the use of different electrochemical methods, namely polarization curve analysis, electrochemical impedance spectroscopy (EIS) and scanning ...

Electrochemical behaviour of N-acetyl-l-cysteine on gold electrode—A tentative reaction mechanism [PDF]

open access: yes, 2007
The electrochemical behaviour of N-acetyl-l-cysteine (NAC) has been investigated by linear and cyclic voltammetry on gold electrode at room temperature. The results showed two oxidation peaks under acid and neutral conditions and only one in basic medium.

Anodic oxide electrets

open access: yesElectronics Letters, 1969
Anodic oxide films on aluminium have been found to be electrets. The direction of the associated electric field implies a distribution of fixed negative charges within the oxide.

Alumite disc using anodic oxidation.

open access: yesJournal of the Magnetics Society of Japan, 1987
Details are given of a method of measuring perpendicular magnetic alumite discs using anodization with an additional new process called “pore widening” which is effective in controlling the coercive force. Electro-deposited fine iron needles were in a single crystalline state, and the perpendicular orientation of magnetization was confirmed.

Electrochemical Evaluation of Compressed Selective Laser Melted AlSi7Mg and AlSi10Mg Alloys in Chloride Environment

open access: yesAdvanced Engineering Materials, EarlyView.
The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

Oxidation Characteristic and Machining Performance of Reaction-Sintered Silicon Carbide Ceramic in Anodically Oxidation-Assisted Polishing

open access: yesInternational Journal of Electrochemical Science, 2016
A novel method for machining reaction-sintered silicon carbide (RS-SiC) ceramic using anodically oxidation-assisted polishing is proposed. Through anodic oxidation of RS-SiC, hardness of the oxidized sample can be reduced, and the soft oxide layer is ...

An electrochemical investigation of the formation of CoSx and its effect on the anodic dissolution of iron in ammoniacal-carbonate solutions [PDF]

open access: yes, 2013
It has been found that the co-presence of cobalt (II) and thiosulphate ions in ammoniacal-carbonate solutions promotes the passivation of iron, under conditions in which it would otherwise continue to dissolve anodically. Electrochemical experiments have

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Impact of the type of anodic film formed and deposition time on the characteristics of porous anodic aluminium oxide films containing Ni metal [PDF]

open access: yes, 2011
Porous anodic films containing nickel were prepared by AC electro-deposition. The porosity of the films was controlled by using different working conditions (anodisation electrolyte, voltage, and time).

Electrochemical Thinning for Anodic Aluminum Oxide and Anodic Titanium Oxide

open access: yesBulletin of the Korean Chemical Society, 2012
For given electrolytes, different behaviors of anodic aluminum oxide (AAO) and anodic titanium oxide (ATO) during electrochemical thinning are explained by ionic and electronic current modes. Branched structures are unavoidably created in AAO since the switch of ionic to electronic current is slow, whereas the barrier oxide in ATO is thinned without ...
