A Framework for Surface Modification by Electrical Discharge Coating using Variable Density Electrodes

Surface modification is the process of altering physical or chemical characteristics work-piece surface. In this paper, various surface techniques have been discussed. One most appropriate technique electrical discharge coating (EDC), in which hard material made to deposit onto a state reverse polarity condition. Different mechanisms carrying out EDC are presented. Deliberate transfer takes place by using electrodes dispersant metal powders into di-electric. A detailed review literature on theme through has conducted. last, framework for conducting employing density same
