Surface Integrity Characteristics in Wire

However, surface integrity of W-EDMed Inconel components is poorly understood. This study presents the characteristics of surface integrity vs. discharge energy in W-EDM of Inconel 718. The results show that the EDMed surface topography shows dominant coral reef microstructures at high discharge energy, while random micro voids are dominant at low discharge energy.
