Electrolytic Deposition of Zn–Ni Alloy from Acidic Sulphate Bath and Their Characterization

By R. S. Bhat, J. Nayak, A. C. Hegde

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.

Induced codeposition of Ni-W alloy coatings using glycerol as additive and their characterization

By 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 …

Influence of CeO2 nanoparticles on the corrosion behavior of electrodeposited Ni coatings

By K. M. Aswathi, Liju Elias, A. Chitharanjan Hegde

Abstract: Nickel-Ceria (Ni-CeO2) nanocomposite coatings were developed on mild steel (MS) substrate using electrodeposition method. The codeposition of the nanoparticles was achieved from the optimized Ni plating bath loaded with CeO2 nanoparticles (particle size <20 nm). Ni and Ni-CeO2 coatings were achieved at a wide current density (c.d.) range from 1.0 to 5.0 A/dm2 under optimal conditions, and their corrosion protection efficacy was examined in 5% NaCl medium. The material property …
