Application of the discharge with liquids for the surface treatment of ancient glass and ceramic objects allows a simultaneous removal of corrosion product layers with the removal of organic pollutants deposited on their surface. Products of the plasma–surface interaction can be simply dissolved into the bulk liquid or can be removed by the liquid flow. The layers deposited on the ancient glass and ceramic surface contain mainly compounds from the surrounding environment with species, mainly alkali metal compounds, originating from the object core. Based on the discharge configuration and its supply, the plasma–liquid–surface interactions can significantly differ.
Diagnostics of Energy Fluxes in Dusty Plasmas

Knowledge of the temperature of micro- and nanoparticles is not solely beneficial for the improvement of processing plasmas. The interaction of small particles with plasmas is still not fully understood. A new, semi-invasive diagnostic tool for plasma–surface interaction could offer the possibility to obtain valuable supplemental information and, thus, to improve the understanding of related basic phenomena. This could, in turn, be of benefit for theoretical and astrophysical questions, as well as for plasma physics and nanotechnology in general.
Section 3: Basic Processes: Plasma/Surface Interactions
Published in Mark A. Prelas, Galina Popovici, Louis K. Bigelow, Handbook of Industrial Diamonds and Diamond Films, 2018
Plasma/surface interaction processes are numerous and complex. They are of extreme importance for the balance of mass and energy transfer, and can affect the volume, as well as influencing the control of the plasma characteristics. For instance, a strong consumption or production on surfaces of an easily ionized species can lead to a major change in the electrical characteristics of the plasma followed by changes in the energetic and chemical composition balances.

Currently, low-temperature plasma sources are widely used in different fields of science, technology, and industry: household use as light sources; production of microelectronics; plasma processing of materials; and scientific research of different aspects of plasma-material interaction, including promising materials for use in fusion reactors. Plasma sources can be based on different principles: ionization of molecules in glow discharges, ionization by electron impact, excitation by radio-frequency (RF) and microwave sources, etc. For applied research in the field of plasma-surface interaction related to the problems of fusion facilities, the most interesting are high-flux plasma generators that simulate plasma fluxes typical for fusion reactors.
