Abstract

The results of the study of phase and dispersed composition of the powders produced by electrical explosion of tungsten wires in the different gases are presented. The influence of electrical parameters (the value of energy input in wire and the arc stage of the explosion) is studied. The factors that make for increasing dispersiveness of nanopowders are the lower pressure of surrounding gas ambient and the use of addition of chemically active gas - nitrogen..

Keywords
