Synthesis of Tungsten carbide nanoparticles in different dielectric through µ-EDM

Abstract

ABSTRACT This article focuses on the morphology, shape, and size of NPs which are crucial steps in nanotechnology. The production of tungsten carbide (WC) nanoparticles and tool wear rate under different voltage and duty factors have been studied in two different dielectrics, i.e., EDM oil and kerosene. It has been seen that the generation of NPs and tool wear rate increases with an increase in voltage at a constant duty factor. The maximum amount of generated NPs was obtained at a duty factor of 20%, and voltage 40 V are 0.1013 gm and 0.0447 gm in EDM oil and kerosene, respectively. The higher value of tool wear rate was observed at duty factor 20%, and voltage 40 V are 0.000278 gm/min and 0.000192 gm/min in EDM oil and kerosene, respectively. The production of NPs is more, and the formation of carbide is less with using EDM oil as compared to kerosene. Field emission scanning electron microscopy (FESEM) image depicts that tungsten carbide nanoparticles are spherical, and carbon is in uneven shapes. Energy-dispersive X-ray spectroscopy (EDX) results reveal that the produced nanoparticles contain tungsten (W), Carbon (C), and Oxygen (O) in both dielectrics.
