Abstract
This review presents the results concerning a comparatively new trend in physics of plasma electrolysis, surface-treatment technology, deposition of coatings, and processes of plasma–electrolyte saturation. Physical and chemical principles of plasma electrolysis are discussed. As shown, this way of materials treatment could improve mechanical, tribological, and corrosion properties of metal wares. Processes of micro-arc oxidation (or plasma–electrolyte oxidation — PEO) are considered, and examples of its application are demonstrated. Processes of electrolyte–plasma quenching of near-surface layers of concrete wares are analyzed; processes of diffusion, directed mass transfer, and doping metallic-wares’ surface layers are considered.
