Electrospark Dispersion in Nanopowder Production for Additive Technologies

  • Published:
Russian Engineering Research Aims and scope

Abstract

A laboratory electrospark system permits the creation of an overvoltage in the gap between dispersible electrodes. Conductive nanopowder may be produced by an electrospark method with a considerable overvoltage in the electrode gap. The production of small powder batches for additive technology by this means is promising and economical.
