In this study, the transfer of insulating material from an electrode to a workpiece with discharge pulses was investigated. A method of transferring a conductive material has already been developed. However, for an insulating material, it is necessary to transform it into conductive electrode to allow discharge. In this report, zinc was used to bind the insulating material in order to form the electrode, and the zinc also works as a medium to transfer the insulating material during discharges. for the transfer of the insulating material as well as the binder of the electrode. It was expected that heat generated by discharges vaporizes all zinc elements and only the insulating material would remain on the surface of the workpiece. In fact, however, it was difficult to remove those zinc elements and a large amount of zinc remained in the layer. In this report, a method of reducing the elements of zinc from the layer was investigated.
