ABSTRACT:
An improved electrical discharge machining electrode permitting improved cutting action to be achieved at the same level of electrical power being applied to the wire electrode. Such improvement is attributable to a particular configuration and the material being employed in the wire electrode which has an iron alloy core coated with an intermediate layer including a copper and zinc heat reaction product on which is deposited an adherent carbon surface coating. The improved method and apparatus for employment of this electrode is also described along with one method to form the multilayer coating on the electrode wire core.
