Electrode for pulsed electrochemical machining

Abstract

In some examples, pulsed electrochemical machining (pECM) system, including an pECM tool comprising a tool body, the tool body comprising an electrode defining a working surface configured to oppose a workpiece during a pECM process; an electrolyte system configured to supply electrolyte to an interelectrode gap between the working surface of the electrode and a target surface of the workpiece; and a power supply configured to generate a pulsed direct current between the one or more electrodes of the pECM tool and the workpiece during the pECM process. The electrode includes an oxidation resistant layer defining at least a portion of the working surface, and a diamond-like carbon coating that defines another surface of the electrode.
