Investigation the Influence of Chemical Components Penetrating the Surface of SKD61 Steel to the Surface Microstructure in PMEDM Process

The Electrical Discharge Machining (EDM) is a machining method that uses the heat to obtain during the discharge of a spark to remove materials from the workpiece. Thus, the process of sparking has changed surface properties. This work investigates the penetration of chemical components on the surface of SKD61 steel after being processed by the EDM method with the mixing of tungsten carbide powder (PMEDM) in to the dielectric fluid affecting the surface microstructure
