Tailoring Electrolytic Deposition of Zn-Ni Alloys for Superior Corrosion Resistance in Harsh Environments
Abstract: Since Zn–Ni alloy coatings are more resistant to corrosion than pure zinc coatings, they are being researched extensively. In this study, Zn–Ni alloy coatings electrolytically deposited from an acidic sulfate bath are investigated. The study looks into how the microstructure, phase composition, and corrosion resistance of the coatings are affected by deposition factors like pH, current density, and electrolyte composition. X-ray diffraction (XRD), potentiodynamic polarization, and scanning electron microscopy (SEM) …

Electrolytic Deposition of Zn–Ni Alloy from Acidic Sulphate Bath and Their Characterization
Abstract: A bath containing ZnSO4.7H2O, NiSO4.7H2O, thiamine hydrochloride (THC) and citric acid (CA) has been proposed. Bright Zn–Ni alloy coatings were developed galvanostatically onto mild steel (MS) and their corrosion resistance and other physical properties were studied. THC was found to improve the brightness and homogeneity of the deposit. The dependency of bath composition, current density (c.d.), pH and temperature, agitation on wt.% Ni were tested. Deposition was carried out under …

Use of Atomic Force Microscopy on Lithium-Ion Batteries
Abstract: Improvement of cutting edge Lithium Ion Batteries (LIBs) shows a quickly developing field of science and innovation. In any case, numerous crucial issues stayed uncertain because of absence of comprehension of surface/interface understanding of LIB on nanometer scale. Here, we survey late uses of nuclear power microscopy to study three key parts of lithium particle batteries specifically strong electrolyte interface, particle transportation and dendrite development. In situ AFM is a …

Square Wave Pulsed Electrodeposition of Chromium from Deep Eutectic Solvent (DES) Based on Choline Chloride
Abstract: Electrodeposition of chromium from hexavalent chromium ion is very toxic, carcinogenic, not environmentally benign, cathodic efficiency is low, and the quality of coating is very poor (due to H2 evolution). Ambient temperature Deep Eutectic Solvent (DES) can be formed by reacting choline chloride (HOC2H4 (CH3)3Cl) with metal salts. These low cost DES are not sensitive to air and moisture and have good electro-conductivity and they do not have vapour pressure. …

Future prospects for DSSCs and its fabrication parameters with efficiency enhancement
Abstract: Dye-sensitized solar cells which combine the unique properties of both the organic compound and inorganic compound have attracted the attention of scientists. Thin film of TiO2 paste deposited on ITO (Indium doped Tin Oxide) acts as one electrode, Carbon electrode acts as counter electrode and ruthenium as the sensitizer. I-/I3- is used as the electrolyte. An increase of output potential when the cell was heated over a short period of …

Review on Electrolytic Process by Refining the Metals
Abstract: Electrolysis is a method of purifying impure metals. The crude metal that needs to be refined serves as the anode in an electrolytic cell while the metal that has been purified serves as the cathode. To ensure that the metal at the cathode is reduced extremely specifically, the electrode potential is chosen. Impurities are left behind in the electrolyte liquid as the metal is transferred from theunrefined metal of the …

A Study on the Effect of Current Density on Electrocatalytic Behavior of Ni–Co Alloy
Abstract: Active, stable and more efficient electrocatalysts are the requirements for water splitting applications. In this direction, the present paper presents the experimental results on electrolytic development of Ni–Co alloy coatings, and their application as electrode material for hydrogen evolution reactions (HER) and oxygen evolution reactions (OER). The Ni–Co alloy coatings were electrodeposited on copper substrate from a sulfate bath, using the glycerol as additive. The deposited coatings were then tested …

Industrial Wastewaters Purifier
Abstract: The main problem in all existing electroflotators for wastewater treatment is the salinization of the space near the cathode during electroflotation, which leads to the formation of salt deposits on the cathode, which heavily cover the cathode surface, which can lead to a complete coagulation of the process. electroflotation cleaning. Another problem is that a dense wire grid of a certain thickness is used as the anode, which increases the …
