Abstract

In the present state of work, a tungsten tool is used for alloying of HSS workpiece material by depositing a hard carbide layer of tungsten and iron through micro-electrical discharge machining (μ-EDM) process. Commercial EDM oil was used as a dielectric that reacts with the tungsten tool electrode to form tungsten carbide over HSS work material. The micro-hardness values and the Energy Dispersive Spectroscopy (EDS) plots proved the appearance of carbide phase of the tool on HSS. X-ray diffraction (XRD) plot suggest the formation of hard carbide phase of tungsten (tungsten carbide) and iron (cementite) on the alloyed surface. The diffusion of tool and dielectric material from the base material (HSS) towards the transition region has been studied by EDS reports.
