A Study on the Effect of Current Density on Electrocatalytic Behavior of Ni–Co AlloyBy Akshatha R. Shetty, Ampar Chitharanjan Hegde
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 …

Induced codeposition of Ni-W alloy coatings using glycerol as additive and their characterizationBy Ampar Chitharanjan Hegde, Liju Elias
Abstract: As a promising coating material to replace hard chromium coating, the development of nickel–tungsten (Ni-W) alloy coatings of good corrosion protection is of great interest in surface coating technology. Further, the effect of plating variables, including additive on the composition of alloys of induced co-deposition is more vagarious than in other types of alloy deposition. In this regard, an alkaline citrate bath has been formulated for electrodeposition of Ni-W alloy …

Magneto-electrodeposition of Sn–Ni alloy Coating for Better Corrosion ProtectionBy Sandhya Shetty, Vaishaka R. Rao, Ampar Chitharanjan Hegde
Abstract: The present paper reports the development of excellent corrosion resistant Sn–Ni alloy coatings from a new pyrophosphate bath by magneto-electrodeposition (MED) approach. First part reports optimization of conditions for deposition of Sn–Ni coatings on mild steel by conventional electrodeposition (ED) method and their characterization. The second part demonstrates how the corrosion resistance of Sn–Ni alloy coatings can be improved drastically by MED method, using same bath. Significant decrease of corrosion …
