Abstract Scope |
The electrodeposition of cobalt from cobalt chloride using eutectic mixture of urea and choline chloride in the molar ratio 2:1 was investigated. The effect of temperature on the cathodic current density, energy consumption, crystalline orientation and surface morphology was studied. At applied potential of 3.0V and CoCl2 concentration of 0.2M, temperature was varied in the range of 343K and 383K to determine the best experimental condition to obtain higher current density. The current density value increased from 24 A/m2 at 343K to 140A/m2 at 383K.This rise was attributed to increased conductivity of electrolyte and better mobility of ions at higher temperature. The energy consumption of 4 kWh/kg was obtained at 383K. XRD confirms the presence of pure cobalt in all the samples. The surface morphology of the deposits showed that there is a significant grain growth at higher temperature due to thermal activation increasing the diffusion of ions. |
