Electrospark deposition (ESD) is a process used for surface modification and repair of materials, particularly metals. It involves creating micro-welding between a workpiece and a material that is to be deposited, typically involving a filler material. The process uses electrical discharges to melt small quantities of the filler material, which then fuses with the surface of the workpiece upon cooling.
