Abstract

Abstract: The main goal of the project is to research and analyze the surface finishing of Hastelloy and surface Modification by electrical discharge coating. Machining is done by Electric Discharge Coating processes using EDM Oil as the dielectric liquid and copper as the electrode. The conventional EDM oils are kerosene, paraffin and transformer Oil extracted from petroleum oil. Electric discharge coating (EDC) is an emerging surface modification Technology to create such hard coatings by using electrical discharges to apply a layer of material to a workpiece Surface to modify and enhance surface properties or create new surface features. The analysis report of this project includes peak current, pulse duration (TOn) and tip wear rate (EWR). Material Removal Rate (MRR), Tool Wear Rate (TRR) and Surface Roughness (Ra), Discharge Voltage, Duty Cycle and the weight of the workpiece before and after machining. Keyword: Hastelloy; Dielectric; Modification; MRR; TWR; Ra
