Correlation of Limiting Currents; Electrodeposition of Copper in Microelectrolytic Cells

Abstract

Limiting currents have been measured using microelectrolytic cells of the type: . Good agreement with existing theory of the correlation of limiting current densities under free convective conditions was obtained for relatively thick (5 mm) electrodes confirming that convection does occur in microcells. For thin electrodes a correlating factor, which is assumed to be related to “edge effect,” is evaluated.
