摘要：
In this reporting, application potential of copper powder added kerosene dielectric media has been compared to that of copper powder added used transformer oil (as dielectrics) during Electro-Discharge Machining (EDM) of super alloy Inconel 718. Improvement in machining performance of Inconel 718 has been studied in purview of machining rate, EDMed surface morphology as well as topography. The following topographical measures viz. roughness average, intensity of surface cracks, thickness of the white layer developed over the EDMed surface have been analysed. EDS and XRD analysis have been conducted to understand the extent of foreign element migration, formation of intermetallic phases, grain refinement taking place during the machining process. The comparative experimental study has finally concluded that copper powder mixed used transformer oil has been the better choice between aforesaid two alternative Powder-Mixed Electro-Discharge Machining (PMEDM) routes in view of machining performance of Inconel 718.
