Effect of Cobalt Concentration on the Microstructure of Nickel-Cobalt Alloy Deposits

Article Preview

Abstract:

Nickel-cobalt alloy deposits were prepared on copper substrate by electrochemical deposition at various cobalt concentrations in electrolytic solution of 0, 6, 12, 18 and 24 g l-1. The deposition was performed at current density of 30 mA/cm2. X-ray diffraction measurements confirmed that all nickel-cobalt alloy films formed have face-centered cubic structure. EDS studies showed that Co content in Ni-Co alloys increased with the increase of cobalt sulfate concentration in the solution. It can be suggested that increasing concentration of co sulfate is the reason for an increase in activity of cobalt ion. The investigations on the electrodeposited Co-Ni alloys have been shown that their microstructure and surface morphology were found to depend strongly on the Co content in the Ni-Co alloy deposited.
