Formation of Taylor Cone Shaped Asperities on Cylindrical Surfaces by Applying Electric Discharges in Pulse [Articol]

Abstract

This paper presents the results of experimental research on Taylor cone shaped meniscuses formation on the surfaces of pieces by applying electric discharges in pulse. It examines the influence of energy stored in the capacitor and of pulse duration on their formation. The modification of piece surface micro-geometry aims to increase the capacity of absorption of radiation and of particle emission. It shows that the size of formed meniscuses depends on the energy regime of machining, on the gap size, on the duration of electric discharges in pulse and on thermal-physical properties of the material used to execute the piece.
