Surface Modification of SKD 61 by Electrical Discharge Coating (EDM/EDC) with Multilayer Rectangular Cross-Section Electrode and Jatropha curcas as Dielectric Fluid

Abstract:

Beside being used as alternative fuel, Jatropha curcas can also be use as dielectric fluid in the Electric Discharge Machining (EDM/EDC). The use of Jatropha curcas as dielectric fluid is starting to grow due to its green characteristic. This paper discusses the effects of using Jatropha curcas combined with rectangular cross section layered electrode for cutting SKD 61 steel. It is then compared to the cutting result of EDM process using combination of kerosene dielectric fluid with solid electrode. The outcomes reveal that cutting process using Jatropha curcas as dielectric fluid in lower current produces higher surface roughness and combination of dielectric fluid with electrode type will determine surface roughness, hardness, and white layer thicknesses.
