Characteristics of nanopowders, obtained by electrical explosion of conductors from tin-lead alloy in air
The phase and element compositions of surface and near-surface layers of particles in powders produced in air by electric explosion of Sn-Pb alloy wires were studied. It is shown that during the wire electrical explosion and subsequent cooling of products, a slight enrichment (3 - 6 %) of powder particle surface layers with lead occurred in comparison to its contents in initial alloy.
