3. Cu electrode produces a thicker recast layer than Cu–Ni electrode.
4. Formation of the recast layer over EDMed surface increases hardness just beneath
the machined surface. Afterward, the hardness profile corresponds to gradually
declined values if the distance is increased towards the interior of the bulk parent
material.
