Dependence of the Composition of Conife Films on the Electrolyte Concentration during Electrochemical Deposition

Abstract

Tikhonov Russia

A study on electrochemical deposition in a triple-component CoNiFe system from a chloride electrolyte solution with equal concentrations of Co, Ni, and Fe was performed. The concentrations used were 0.48; 0.083; 0.00625 mol/l, and the temperature was 70°Ð¡. The relative content of the components in the film approached the composition of the electrolyte, though the concentration of each component was slightly decreased. The dependence of the composition of films on the current density is explained by concentration polarization.
