ELECTRODEPOSITION USING ROTATING CYLINDER ELECTRODE OF COPPER IN PRESENCE OF ORGANIC COMPOUNDS

摘要

This study shows the effect of using different organic compounds as accelerators for copper electrodeposition. High deposition rate is attributed to the enhanced mass transport of copper ions toward the metal surface and lowering the viscosity through the acidic bath using the rotating cylinder technique. The effect of different concentrations of organic compounds in the process of electrodeposition of copper from acidified copper sulfate solutions, has been studied at different temperatures, a node type, different rotation speeds, and additive concentration due to the changes in the physicochemical properties of the mixture. Overall mass transfer correlations have been obtained using the dimensional analysis method. The results agreed with the previous studies of mass transfer to rotating cylinders in turbulent flow systems.
