Theory and technique of manufacture of electrode-tool materials for electroerosion machining

Abstract

In the electrospark machining of carbides of the transition metals, the character and extent of their erosion depend on the form and energy of the discharge pulses and also on the nature and relative strengths of the Me-C and Me-Me chemical bonds. With increase in electrical pulse energy, the explosive action on the electrodes becomes more intense, as a result of which the carbides suffer greater attack through melting, evaporation, and mechanical disruption.
