Abstract

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.
