Plasma formation in the air medium under ordinary pressure and its interaction with solid metal surfaces

Abstract

The conditions for obtaining an electrical discharge plasma in a gaseous media, as well as its application in different fields of nanotechnology, are analyzed in this paper. Plasma production under the investigated conditions avoids the use of auxiliary equipment for the preventive ionization of the active media, which does not require synchronization between the base discharge and the moment at which the ionization in the gap is maximal. As a result of the interaction of the produced plasma with different material surfaces, structures of nanometer order were obtained, and the plasma itself can be applied at the construction of quantum generators in non-aggressive gaseous media as well as at the sterilization of objects in medicine.
