The nickel-copper alloy (70:30) prepared by metallurgical route is currently employed in marine environments because of its good resistant to corrosion. This alloy forms a thin protective surface layer when exposed to marine atmosphere, and thus provides its corrosion resistance. Electrodeposition of nickel copper alloy from sulphamate acetate based electrolyte is a new and novel approach and was experimented. The detailed study was performed on the effect of electrolyte composition, current density and pH for the preparation of alloy deposit; the prepared alloy deposit particle size is of 78 nanometer and the surface morphology of the alloy deposit was characterized with XRD, SEM, EDAX, and AFM. Nickel copper alloy deposited from the sulphamate acetate based electrolyte operated at a temperature of 30°C, with a pH of 6.6 and at 3A/dm2, produces nickel-copper (70:30) alloy deposit. The corrosion behaviour of this alloy deposit was studied by potentio-dynamic polarization method; the corrosion current of nickel is 8.67μAcm-2 and the nickel copper alloy is 2.65μAcm-2.
