  Production of Compositionally Modulated Nanolayer Zn–Ni Alloy Coatings and Their Corrosion Behaviours

  By R. S. Bhat, Ampar Chitaranjan Hegde

  Abstract: Compositionally modulated nanolayer alloy (CNA) coatings of Zn–Ni having alternatively the same compositions have been developed galvanostatically on mild steel from single bath technique (SBT) using square current pulses. Sulphanilic acid and citric acid (CA) were used as additives. Modulation in the composition of alloys were introduced by passing a different switched cathode current densities (SCCD’S) using sophisticated power sources. Variety of CNA coatings was developed under different conditions of …

  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. Deposition was carried out under …
