Coupled oscillating cobalt electrodes

Experimental studies have been carried out with two different coupled electrochemical oscillators. The First study was described in the preceding article. In this present paper we consider cobalt electrodes in hydrochloric acid chromic acid electrolytes, Two electrodes, one of which was embedded in a rotating disk and the other of which was in a nonrotating disk parallel to the first, were used. Several types of phenomena due to coupling were observed. Each electrode can drive the other. Phase-locked oscillations were observed when neither, either, or both of the electrodes were held at a potential where oscillations occur independently
