Abstract

The phase and element compositions of surface and near-surface layers of particles in powders produced in gaseous argon by electric explosion of Cu-Ni alloy wires were studied. It was established that powders produced from Cu-Ni alloys are phase heterogeneous. Their size distribution function is three-modal. Their dispersivity increases with the increase of the energy input into a conductor. The principal phase stabilizing in electroexplosion end-products from alloys Cu-Ni23 and Cu-Ni45 is intermetallic compound Cu0.81Ni0.19. Apparently, the metal phases of copper or nickel are located in the central areas of the particles. A mechanism of particle formation during electrical explosion of wires was proposed.
