Abstract
The results on cathode material erosion under action of atmospheric-pressure glow discharge in argon flow powered by unipolar microsecond voltage pulses following with a pulse repetition rate up to 100 kHz are presented. An amplitude of the current pulses was from 500 to 800 mA. The presence of erosion products from the cathode material in the plasma was determined through the detection of ionic and atomic metal lines in its emission spectrum, as well as through analyzing powder samples collected during the operation of the discharge system. It has been shown that, depending on the method used to create the temperature conditions required for cathode erosion, different nanoparticles are formed. These nanoparticles differ in their morphology and chemical composition.
期刊介绍：
Bulletin of the Russian Academy of Sciences: Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It presents full-text articles (regular, letters to the editor, reviews) with the most recent results in miscellaneous fields of physics and astronomy: nuclear physics, cosmic rays, condensed matter physics, plasma physics, optics and photonics, nanotechnologies, solar and astrophysics, physical applications in material sciences, life sciences, etc. Bulletin of the Russian Academy of Sciences: Physics focuses on the most relevant multidisciplinary topics in natural sciences, both fundamental and applied. Manuscripts can be submitted in Russian and English languages and are subject to peer review. Accepted articles are usually combined in thematic issues on certain topics according to the journal editorial policy. Authors featured in the journal represent renowned scientific laboratories and institutes from different countries, including large international collaborations. There are globally recognized researchers among the authors: Nobel laureates and recipients of other awards, and members of national academies of sciences and international scientific societies.
