Abstract

The factors influencing the structure and tribological properties of materials and coatings formed in an electrolyte plasma are determined. The main directions of microplasma modification of the friction surface of parts are considered: increasing its hardness and wear resistance, obtaining corrosion-resistant and decorative coatings, reducing the material consumption of the friction unit as a whole and replacing expensive materials. A multiple increase in the service life of hardened tribo-couplings is shown. Examples are given of obtaining ceramic materials with a solid lubricating filler that successfully operate under conditions of dry friction or limited lubricant supply. The basics of the original technology for obtaining a mineral-ceramic material, which is a matrix of aluminum oxide and dispersed diamond inclusions, are outlined and its properties are shown. Examples of the implementation of ceramic composite materials formed by microplasma oxidation in real tribodevices and the results of experimental studies of their tribotechnical characteristics are given.
