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...

Abstract. The potentiodynamic experiments of the nickel effects on zinc electrodeposition have been done to understand impact Ni impurities electrowinning Zn from spent pickling liquor. chloride solutions concentrations 90 and 1 g/dm3 were used as electrolytes. latter was also mixed with in experiments. All runs carried out at room temperature 40 mV/s continuous polarization speed 1/s sampling ...

The current paper introduces for the very first time recently invented electrodeposition-redox replacement (EDRR) method in continuous leaching-recovery-solution purification process. mini-pilot study reveals that longer duration of EDRR process is beneficial as it increases gold recovery per stage and decreases specific energy consumption EDRR. This extraordinary behavior postulated to be inhe...

Anodic aluminium oxide (AAO) templates for multi-walled carbon nanotube (MWCNT) growth were produced by anodization of aluminium followed by pulse-reverse electrodeposition of cobalt inside the AAO pores. Cobalt functioned as the catalyst for H2/C2H2 chemical vapour deposition (CVD) growth of fairly well graphitized MWCNTs initiating inside the majority of the AAO pores and quickly growing beyo...

Photocatalytically active nanostructures require a large specific surface area with the presence of many catalytically active sites for the oxidation and reduction half reactions, and fast electron (hole) diffusion and charge separation. Nanowires present suitable architectures to meet these requirements. Axially segmented Ag|ZnO and radially segmented (coaxial) TiO2-Ag nanowires with a diamete...

Electrodeposition is a novel and benign fabrication method which excellently combines electrochemical deposition mechanism additive manufacturing to realize the processing of metal-based structures layer-upon-layer. Herein, an unusual (AM) proposed based on deposition. Notably, three-dimensional forming metal by local conductive samples (PLA-CNTs7wt%) as cathode through selective was realized. ...

This study shows the electrodeposition of Fe-Cr-Ni alloys using advantages a stepped direct-current deposition in Cr(III)-containing electrolyte, and its influence on pH value. The resulting coatings are uniform free microcracks, with Cr content around 30% thicknesses above 10 µm. current mode (direct current, direct pulsed current) development is investigated correlated arising microstructure ...
