Abstract

An analysis of approaches to studying the interaction of the surface with a stream of charged particles is presented in order to increase the efficiency of the process of low-temperature plasma modification of the surface layer. The results of the analysis showed that it is theoretically difficult to study the interaction, therefore, it is interesting to study it empirically using electrochemistry methods that allow us to investigate the phenomena of mixing and spreading of a liquid placed on the surface caused by molecular interaction processes. An off-the-shelf technology for studying surface interaction for charged particles flow in a low-temperature plasma has been found. The technology is based on the surface interaction for a particle flow simulator, using an aqueous 3,0 % NaCl salt solution. During the course of studying, it was found, firstly, that the results of interaction are actively influenced by chemical processes between the surface and the ions of the solution, depending on the value of the potential of the electric field applied to the surface, as well as due to its microrelief, and secondly, that the main boundary process running under surface interaction and solution is adsorption. The data of the analysis of the effects of exposure to the plasma surface are presented. They proved the reliability of study results, since the course of chemical and adsorption processes also take place. In general, the materials presented in the article allowed making conclusion that the developed technology makes it possible to determine the conditions that ensure an increase in the efficiency of the low-temperature plasma modification process contributing to the improvement of both surface (electrochemical) and volumetric (physical mechanical and electrophysical) properties if it is used either in the initial state or in the state changed by plasma particles.
