“…The former are able to steadily counteract external force perturbations, while the latter can rearrange in the direction of external forces. Taken together, this increases the stability of the product surface layer during operation, especially under extreme conditions [12,13].…”

“…One of the main areas of research in this regard is the research into the effect of high-frequency (ω ~ 2π • 10 6 -2π • 10 8 s −1 ) (HF) low-pressure gas discharge on the product surface, which was studied experimentally [4][5][6] and theoretically [7][8][9][10][11][12][13][14]. Earlier, in [15][16][17][18][19], the effect of a low-pressure combined gas discharge on the metal surface was examined. The low-temperature plasma generated in the original (developed by the authors) processing plant is formed near the product surface under the influence of two factors: microwave (1.54 • 10 10 s −1 ) electromagnetic field generated by the magnetron in the resonator chamber, and the electrostatic field that occurs when a static bias potential is applied to the product ϕ 0 ≈ 50-250 V. In this case, the input microwave power is only 30-150 W, which is significantly lower than the power of the units P 0 ~ 200-500 W used to process products with HF discharge plasma [19].…”

The properties of an asymmetric microwave gas discharge that occurs in an argon-filled resonator chamber of a processing plant near the surface of a metal product during the formation on it of a composite structure are experimentally and theoretically investigated. It is shown that with a significant difference between the electrode dimensions, the smaller of which is the product, and the larger are the resonator chamber walls, there is an area of a high energy density of the microwave field near the surface of the product, in which electrons are accelerated to high energies up to hundreds of eV. Diffusing from this area, high-energy electrons are decelerated due to inelastic scattering on the gas molecules that fill the resonator chamber, ionizing them or promoting them to an excited state. We have obtained a differential equation and found its solution which describes the diffusion process accompanied by the loss of energy by high-energy electrons, within the framework of the continuous deceleration model. The estimates of the main physical parameters characterizing the microwave gas discharge plasma are found. The conditions that are most favorable for the energy transfer from the microwave field to the plasma electron subsystem and the product surface treatment are determined.

“…One of the ways to increase the serviceability of products in terms of wear resistance is the creation of technologies and equipment for product surface layer hardening [1,2], in par ticular, plasma ones [3]. The latter include the equipment (unit) developed by the authors and technology that allow the surface layer formation of nanocomposite dissipative chemi cally stable coatings [4,5] consisting of:…”

The properties and effects of a combined gas discharge, obtained by superimposing ultrahigh frequency electromagnetic and electrostatic fields on the surface of metal products, have been studied. Estimates for the main physical properties characterizing the discharge have been obtained. The paper shows that the properties of a combined discharge essentially depend on the sign of the constant electric potential of the workpiece. In the case of a positive potential, there is a substantial hardening of the metal surface layer. Blanket coating formation, which is a nanocomposite twophase structure, has been recorded.
