Abstract
An entry wire passes through a furnace containing zinc vapor in an inert atmosphere. While passing through the furnace the wire is heated by the Joule effect, by passing through it an electrical current produced by a generator, which rapidly heats it to the appropriate temperature. This produces an electrode wire having a thicker surface layer of diffused copper-zinc alloy, so that spark erosion machining is accelerated. The manufacturing method is fast and low in cost.
