Work peculiarities of powerful and low-temperature pulsed plasma flow accelerators, and plasma focus devices, were considered on the technological application point view. A common and characteristic feature for all installations is the pulsed nature of plasma formation. At first, the results of researches on the use of a pulsed vacuum-arc unit in nano-engineering are presented. The powder materials were obtained in the form of clusters, in the composition of which spherical particles were found. In next experiment, the powerful plasma flow was directed to a graphite target for its sputtering, and then the plasma was condensed onto a nearby steel substrate. The presence of precipitated graphite particles of spherical shape and dimensions of 110–900 nm is shown. The results of the study allow to make a conclusion about the possibility of obtaining spherical particles with a controlled composition when using different targets.
