Inconel 718 is an extremely hard and difficult-to-cut material used extensively in manufacturing because of its superior wear and corrosion resistance. Microelectrical discharge machining (micro-EDM) is one of the effective methods of machining this extremely hard material. However, due to short circuiting and arcing, the surface of microholes produced by micro-EDM has black traces and cones. This study investigates the influence of molybdenum disulfide (MoS2) powder suspended in dielectric fluid on the performance of micro-EDM of Inconel 718 with focus in obtaining quality microholes. It was observed that MoS2 powder suspension with 50 nm of size and 5 g/l of concentration can produce better quality microholes in Inconel 718. Moreover, it was also found that 50 nm MoS2 powder was the best powder size to achieve the highest material removal rate.
