It is well known that the types of automotive corrosion can be divided into perforation and cosmetic corrosion. Although mechanism has been studied extensively, not yet clarified. The authors investigated behavior cold-rolled steel sheets without galvanizing with an in-situ observation device. After coating samples by cathodic electrodeposition (ED), sample surface was scribed a cutter. Corrosi...

The Fe nanowires were prepared by Ac electrodeposition method. The two steps anodized aluminum oxides (alumina) were used as templates for electrodeposition of magnetic nanowires. Sulfuric acid was used to anodize aluminum. The pours diameter and growth rate of alumina were investigated. The FeSO4 electrolyte was used for growth of nanowires. The prepared magnetic nanowires were characterized b...

cofecu nanowires were deposited by pulsed electrodeposition technique into the porous alumina templates by a two-step mild anodization technique, using the single-bath method. the electrodeposition was performed in a constant electrolyte while cu constant was controlled by electrodeposition current. the electrodeposition current was 3.5, 4.25, 5 and 6 ma. the effect of electrodeposition current...

This study examined the characteristics of calcium phosphate coatings formed on untreated and H2O2-treated titanium substrates by electrodeposition in a modified simulated body fluid (SBF). A porous coating comprising of mainly hydroxyapatite (HA) was formed on the H2O2-treated titanium substrate by electrodeposition. This coating was transformed into carbonate and calcium-deficient HA layers w...

Electrodeposition of platinum and silver into hydrophobic and hydrophilic microporous silicon layers was investigated using chemically-modified microporous silicon electrodes. Hydrophobic microporous silicon enhanced the electrodeposition of platinum in the porous layer. Meanwhile hydrophilic one showed that platinum was hardly deposited within the porous layer and a filmy growth of platinum on...

calcareous deposits formed on the part of steel that cathodic reactions occur on their surface. the purpose of this research is an investigation of the effect of potential on crystal form of the calcareous deposits and effect of them on the corrosion resistance of the mild steel in natural seawater. the electrochemical tests such as impedance and polarization tofel tests were used in order to i...

Abstract According to the requirements for anode materials of safe and high‐capacity lithium‐ion batteries (LIBs), various Sn/TiO 2 SnO /TiO composite have been developed, but no reports yet combined them by a simple fabrication method. Herein, novel approach is reported nanoporous TiO –TiN/Sn–SnO films successive Ti anodization cathodic hybrid electrodeposition Sn in nitric acid‐based aqueous ...
