Abstract

Cobalt electrodeposition was carried out using sulphate and chloride baths to investigate the effects of electrolysis factors on the crystal orientation and morphology of the deposits. The preferred orientation of Co deposited from the sulphate baths changed from (0 0 0 2) to (1 1 2̄ 0) plane with an increase in the deposition overpotential and the deposits showed the largest grain size with a smooth surface in the low overpotential region. On the other hand, no dependence of crystal orientation and morphology on deposition overpotential was found in chloride baths.
