Abstract
The purpose of this study was to design an electrode (anode) that would yield relatively uniform primary current distribution over a cylinder with hemispherical ends (cathode). The designing was carried out using the electrolytic trough method of mapping equipotential surfaces between electrodes. Cathode current distributions derived from the equipotential maps were compared with the distributions of electrodeposited chromium. Deviations between the two distributions, which are a measure of the effect of anode polarization during chromium plating, were generally small. Primary cathode distributions with maximum deviations from the mean of about 10 per cent are readily obtainable using relatively simple anode geometries.
