Investigation of Surface Modification of 60CrMoV18-5 Steel by EDM with Cu-ZrO<sub>2</sub> Powder Metallurgy Green Compact Electrode

Electrical discharge machining (EDM) is a non-conventional machining process, which is mostly used for machining of difficult-to-cut materials. These materials are often used in engineering applications that require improved surface properties; thus, surface modification is desirable in these cases....
