TL;DR: In this article, a surface modification method by electrical discharge machining with a green compact electrode has been studied to make a thick TiC or WC layer, where the powder is suspended in working oil like kerosene and the use of a thin electrode and a rotating disk electrode are expected to keep powder concentration high in the gap between a workpiece and an electrode and to accrete powder material on the workpiece.

TL;DR: In this article, a metal plate or metal mesh is arranged on the surface of a ceramic insulator as an assisting electrode to keep electrical conductivity on the work piece during the machining.

TL;DR: In this paper, a synthetic consideration of electrode wear phenomena in electrical discharge machining is presented, where the authors deal with a synthetic approach to evaluate the wear rate of an electrode in the stationary state of machining, taking account of turbostratic carbon on the electrode.

TL;DR: In this paper, a new method of surface modification by electrical discharge machining using composite structured electrode surface modifications on work pieces of carbon steel or aluminum were carried out in hydrocarbon oil using composite electrodes Composite electrode consists of green compact products or sintered products Copper, aluminum, tungsten carbide and titanium were used for the material of the electrode, it was revealed that there existed the electrode material in the work surface layer and the characteristics of the surface of raw material remarkably changed

TL;DR: In this paper, a new process of finish machining on free-form surface is proposed, which consists of cutting an electrode and a work by a machining center, removing cusps of the electrode and the work by EDM and finish EDM with powder suspended working fluid.
