EFFECT OF THE CIRCUIT PARAMETERS ON THE ELECTROLYTES IN THE ELECTROCHEMICAL DISCHARGE PHENOMENON

The electro-chemical discharge (ECD) phenomenon is a process producing electrical discharges in electrolytes by the application of voltage t o an electrolytic cell. This process has the advantage of machining no n-conducting material kept in the vicinity of the discharge. The study in this paper explores the influence of external circuit parameters o n the discharge process. The experimental results of average voltage a nd current with NaOH and KOH electrolytes of 2, 5, 10 M concentrations with different circuit configurations are reported. The instantaneous voltage-current behaviour during discharge at 60 V of NaOH, KOH and H Cl electrolytes are reported also for concentrations of 2 and 5 M. The best circuit configuration for the machining of non-conducting materi al is discussed.
