Electrochemical Properties of Co Films by Electrolytic Deposition
Asian Journal of Chemistry,
Vol. 28 No. 10 (2016): Vol 28 Issue 10
Abstract
Both electroless-deposited CoP and CoFeB films and electro-deposited Co films are formed on rapid-quenched amorphous alloy ribbons. These polycrystalline Co-based films were obtained with different preferred orientations, surface structures and magnetic properties, from the species of substrates. Electrochemical characterizations by means of polarization curve clarified the catalytic activity of electrodes and the over potential, for electroless- and electro-depositions, respectively. These electrochemical properties may affect the first stage of deposition, to determine the structural and magnetic properties of the films. It is found that the structural and magnetic properties of non-electrically deposited films are determined by the initial step of electrochemical parameters dependent on the species of substrate. This is because the nucleation and crystal growth are related to electrocatalysis of substrate electrode for anodic oxidation of the reductant in non-electric deposition and over-potential of electrodeposition, whose parameters are dependent on the alloy element of substrate. The properties of both non-electrically deposited and electrically deposited films of a few micrometers thick are influenced by the initial behaviour of electrolytic deposition.
