Abstract

The experimental results aimed at modification of metal surface micro geometry by applying electric discharges in impulse are presented in this paper. Taylor cone-shaped asperities were extracted from the metal piece on the flat and cylindrical surface. SEM and EDX analysis of the processed surfaces were investigated
