ABSTRACT:
An electrode for electrical devices subject to electrical erosion effects such as spark erosion. Selected areas of the surface of the firing end of the electrode are provided with a thin coating of electrical-erosion resistant material such that the erosion of the electrode adjacent the coating produces a thin edge which promotes current emission therefrom. Preferably the coating is a layer of aluminum from 0.5 mil to 10 mils in thickness. In further embodiments, the electrode is aluminum or an alloy thereof coated with an unalloyed aluminum. In other embodiments, a longitudinal coaxial hole or one or more slots are provided in the firing end of the electrode.
