The effects of the pause to pulse ratio in the regime of pulsating overpotential on the formation of honeycomb-like structures
(Elsevier Science Inc, New York, 2009)
The formation of honeycomb-like structures in the pulsating overpotential (PO) regime was examined by scanning electron microscopy (SEM). The honeycomb-like structures obtained with a square-wave PO of different pause to ...
A Novel Route for Electrolytic Production of Very Branchy Copper Dendrites under Extreme Conditions
(IOP Publishing Limited, 2021)
Copper electrodeposition in a form of powder was examined using the pulsating overpotential (PO) regime from the sulfate electrolyte without or with an addition of various concentrations of chloride ions. Morphological and ...
Comparison of open porous copper structures obtained by the different current regimes of electrolysis
(Elsevier, 2012)
Formation of open porous copper structures by the electrodeposition processes in the hydrogen code-position range was considered. Morphologies of copper deposits obtained by the reversing current (RC) regimes at the same ...
Fundamental aspects of pulsating current metal electrodeposition VIII: The effect of pause-to-pulse ratio on microthrowing power of metal deposition
(Elsevier, 1984)
The effect of a pulsating current on the microthrowing power of metal deposits in the early stage of deposition was investigated by scanning electron microscopy. It is shown that at the same average current density the ...
Electrodeposition of Ni, Co and Ni–Co alloy powders
(Elsevier, 2006)
In this paper the polarization characteristics of the processes of Ni and Co powders and Ni-Co alloy powders electrodeposition from ammonium sulfate containing supporting electrolyte are investigated as a function of Ni ...
Electrodeposited Pd and PdNi coatings as electrodes for the electrochemical oxidation of ethanol in alkaline media
(Springer, New York, 2017)
Electrodeposition of Pd and PdNi coating samples of different thicknesses, depending on the coating composition and current efficiency, was achieved galvanostatically on the rotating Au disc electrode from the plating bath ...
Fundamental aspects of plating technology II: Morphological aspects of metal electrodeposition from complex salt solutions
(Elsevier, 1983)
It is shown that the improved quality of electrodeposits obtained from ammonium complex salt solutions compared with deposits obtained from simple salt solutions is due to the decrease in the exchange current density value ...
Fundamental aspects of pulsating current metal electrodeposition IX: The prevention of spongy deposit formation on inert substrates
(Elsevier, 1984)
It is shown that spongy deposits are obtained under d.c. conditions and that compact deposits are obtained in pulsating current (PC) deposition with high pause-to-pulse ratios at the same average current density and ...
Some aspects of current density distribution in electrolytic cells I: Dendritic growth of cadmium at the cathode edge in galvanostatic electrodeposition
(Elsevier, 1983)
The equivalent electrical resistance of a cell with plane parallel electrodes is described by a simple mathematical model. The limits of this model were determined experimentally. The relation between the overpotential at ...
Electrochemical deposition and characterization of Zn /Co alloys and corrosion protection by electrodeposited epoxy coating on Zn /Co alloy
(Elsevier, 2002)
Zn-Co alloys electrochemically deposited on steel under various deposition conditions were investigated. The influence of deposition current density, temperature and composition of deposition solution on the phase structure ...
