Galvanostatic Electrophoretic Deposition of Yttriumsilicate on C/C-Si-SiC Composites

Key Engineering Materials, 2009
The use of carbon fibre reinforced carbon composites in oxidizing atmospheres is limited to temperatures below 400 °C. To benefit from their excellent mechanical strength that is still preserved at high temperatures, suitable oxidation protection coating systems have to be developed.

Performance evaluation of galvanostatically deposited nickel oxide electrode for electrochemical supercapacitors

Journal of Materials Science: Materials in Electronics, 2017
Nanostructured nickel oxide (NiO) electrode has been prepared using electrochemical work station operated on galvanostatic mode in supercapacitor application. Crystalline cubic structure and nanoplate-type of morphology of synthesized NiO electrode was confirmed from X-ray diffraction and scanning electron microscopy analysis respectively.

Galvanostatic deposition of Cu2O layers through the electrogeneration of base route

Journal of Materials Science Letters, 1998
The dependence of the cell voltage on deposition time for current densities of 0.3, 0.6, 0.9, 1.2 and 1.5 mA cm ˇ2 is shown in Fig. 1. The voltage is seen to increase with current density for a constant deposition time. At higher current densities greater than 0.9 mA cm ˇ2 , the voltage stabilizes at shorter duration.

Galvanostatically Deposited Ptni Thin-Films As Electrocatalytists for the Hydrogen Evolution Reaction

ECS Meeting Abstracts, 2020
Hydrogen renders high energy density without any direct carbon emissions, which makes it an ideal energy carrier [1]. PtNi nanomaterials exhibit high catalytic activity for hydrogen production through the hydrogen evolution reaction (HER), in some cases superior to bare Pt [2] and with lower cost due to the replacement with Ni.

Simulation of galvanostatic growth of polycrystalline Li deposits in rechargeable Li batteries

Electrochimica Acta, 2001
This brief communication is a preliminary attempt to apply models developed for electrochemical deposition of metals from aqueous solutions or molten salts (passivation-free condition), to the more complicated case of Li deposition from nonaqueous solutions. The model systems chosen were lithium electrodes in rechargeable, commercial Li (metal)–LixMnO2

Deposition of thin cobalt films onto silicon by galvanostatic and potentiostatic techniques

Journal of Materials Science, 2009
In this study, thin cobalt films were electrodeposited directly onto n-Si (100) using two different electrodeposition techniques: galvanostatic and potentiostatic. The morphological difference between galvanostatic and potentiostatic deposits was observed by atomic force microscopy (AFM) and X-ray diffraction (XRD).

Working electrode polarization in galvanostatic deposition of amorphous Co-P ferromagnetic alloys

Solid State Ionics, 1993
Abstract Studies of the evolution of cathode potential with increasing current densities have been performed in electrodeposition processes under different bath conditions. The role of the constituents of the deposition bath in the final result is discussed as well as the possibility of exerting a potentiostatic control of the composition of the ...

Re-Crystallization of CZTS Solar Cell Materials Prepared by Galvanostat Electro-Deposition

ECS Transactions, 2013
Quaternary Cu2ZnSnS4 (CZTS) films were successfully obtained on Mo/(soda lime glass) substrates by one-step electro-deposition. The process was more efficient than other electro-deposit processes. Electrolytic aqueous was prepared using CuSO4, ZnSO4, SnSO4 and Na2S2O3 mixing solution.

Characteristics of UV sensors using ZnO nanostructures synthesized by galvanostatic electrochemical deposition

2012 IEEE Sensors, 2012
In this study, we demonstrate the ZnO nanorods (NRs) and nanocombs (NCs) by simple galvanostatic electrochemical deposition process. The ZnO nanostructures act as high ultra-violet (UV) sensing material due to high aspect ratio. The photoluminescence (PL) spectra and time-dependent photo response of the ZnO nanostructures grown on Au/Si has exhibited ...
