The study of Zn–Co alloy coatings electrochemically deposited by pulse current [PDF]

Hemijska Industrija, 2012
The electrochemical deposition by pulse current of Zn-Co alloy coatings on steel was examined, with the aim to find out whether pulse plating could produce alloys that could offer a better corrosion protection. The influence of on-time and the average

Pulsed Current Constructs 3DM Cu/ZnO Current Collector Composite Anode for Free-Dendritic Lithium Metal Batteries

Batteries, 2023
Although lithium metal is an ideal anode material for achieving high-energy-density lithium-based batteries, the uneven deposition/exfoliation process of lithium during cycling easily triggers the formation of lithium dendrites and dead lithium, which ...

ELECTRIC DEPOSITION OF TIN-LEAD ALLOY BY PULSE CURRENT

IZVESTIA VOLGOGRAD STATE TECHNICAL UNIVERSITY, 2021
The process of electrodeposition of a tin-lead alloy from hydrofluoride electrolytes by pulsating currents has been investigated. The influence of the electric mode on the alloy composition and properties of the resulting precipitates was studied: current efficiency, microhardness, specific electrolytic resistance, and internal stresses of the ...

A fluid model of pulsed direct current planar magnetron discharge

Scientific Reports, 2023
We simulated a pulsed direct current (DC) planar magnetron discharge using fluid model, solving for species continuity, momentum, and energy transfer equations, coupled with Poisson equation and Lorentz force for electromagnetism. Based on a validated DC

Non-Stationary Electrolysis of a Tin-Copper Alloy

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2023
Electrochemical coatings with a tin-copper alloy were obtained by the method of non-stationary electrolysis. The influence of the parameters of the pulsed-reversed currents (duty cycle, frequency, ratio of the duration of the forward and reverse pulses ...

Superconducting MgB2 thin films by pulsed laser deposition [PDF]

, 2001
Growth of MgB2 thin films by pulsed laser deposition is examined under ex situ and in situ processing conditions. For the ex situ process, Boron films grown by PLD were annealed at 900 C with excess Mg.

Cathodic Arc Deposited CrAlSiN Coatings by Pulsed Current Input

DEStech Transactions on Environment, Energy and Earth Sciences, 2017
Cathodic arc deposition technique is one of the green processes of the physical vapor deposition (PVD) systems. In this study, Cr and CrAlSi dual metal targets were used in order to synthesize CrAlSiN coatings. By using the cathodic arc pulsed current techniques, three different settings of pulsed current duty cycles were used.

Superconducting properties of nanocrystalline MgB$_2$ thin films made by an in situ annealing process [PDF]

, 2001
We have studied the structural and superconducting properties of MgB$_2$ thin films made by pulsed laser deposition followed by in situ annealing. The cross-sectional transmission electron microscopy reveals a nanocrystalline mixture of textured MgO and ...

Morphological, Chemical, and Biological Investigation of Ionic Substituted, Pulse Current Deposited Calcium Phosphate Coatings [PDF]

Materials, 2020
Ionic substituted calcium phosphate coatings (iCP) have been prepared by the electrochemical pulse current deposition technique with an alternate pulse on and off time of 5 ms onto a titanium alloy substrate. The elemental distribution and morphology of the deposited layers have been extensively studied by scanning electron microscopy (SEM), energy ...

Effect of high pulsed current on gold deposits.

Journal of the Metal Finishing Society of Japan, 1988
The effect of high pulsed crrent on the properties of electrodeposited gold film was investigated. The deposits were analyzed by means of an electron microscope and X-ray diffraction, and it was found that the corrosion resistance of gold films was far better when formed by high pulsed current than when formed by direct current.
