Abstract

Nickel was electrodeposited using nickel sulphamate and nickel chloride in ethylene glycol under different plating conditions. Bright and adherent nickel was obtained at a current density of l00 A m⁻² at 40°C using a mixed electrolyte in ethylene glycol. The effect of current density and bath temperature on the cathode current efficiency, microhardness, and structure of the deposits obtained has been studied. The microhardness of the deposits declined with increasing annealing temperature. Studies using transmission electron microscopy and X-ray diffraction revealed a preferred orientation to some extent at different current densities. The results have been explained taking into account the hydrogen content in the deposits. The influence of interrupted direct current has also been investigated.
