Effects of Constant Magnetic Field on Electrodeposition of Co-W-Cu Alloy

Abstract

The paper presents a study of the effect of constant magnetic field (CMF) on the basic processes of Co-W-Cu alloys electrodeposition. The alloys electrodeposited in the presence of CMF were more homogeneous and smooth than those obtained without CMF. The reason for these changes was the fact that the Lorentz force, generated in CMF, caused the magnetohydrodynamic (MHD) effect. Electrolyte motion under the influence of CMF caused an increase of cobalt and tungsten content with a simultaneous decrease of copper content in the alloy. The presence of the magnetic field during plating leads to significant greater corrosion resistance and smaller roughness.
