“…Решение проблемы повышения долговечности осуществляется за счет упрочняющей обработки поверхностного слоя изделий [1][2][3]. К известным методам плазменной упрочняющей обработки относятся: термоупрочнение [4][5][6], ионно-плазменное диффузионное внедрение [7][8][9], ионно-лучевая упрочняющая обработка [10,11], MPACVD-метод (Microwave Plasma Assisted CVD) осаждения поликристаллических алмазных пленок [12][13][14], позволяющие изменять свойства поверхностного слоя и способствующие повышению его твердости.…”

The paper shows that upon ignition of the combined gas discharge in the resonator chamber, there appears a double layer with diode properties that consists of layers of positive and negative charges surrounding the workpiece. An increase in the level of microwave power supplied to the chamber leads to a decrease in the equivalent diode resistance in open and closed modes and an increase in the current flowing through the unit. The ions of the process gas (nitrogen or argon) ionized by the microwave field fall on the product surface and diffuse into it as a result of the thermal diffusion process, which hardens the surface layer. The product is heated when a positive bias potential is applied to it by a stream of high-energy electrons arriving at the surface and accelerated to energies of tens and hundreds eV in the discharge acceleration zone. Ion-plasma implantation leads to a significant increase in the strength, wear resistance and corrosion resistance of the surface of the processed product.

“…Currently, many different methods of surface hardening of the tool are used, which have their advantages and disadvantages [3][4][5]. An unique position among such processes is occupied by chemical-thermal treatment (CTT) [6][7]. For example, nitriding is widely used to increase the reliability and durability of a wide range of steels, both structural and tool [8][9].…”

Abstract. The article is devoted to the study of the gas nitriding process, which makes it possible to obtain high-quality diffusion layers in high-speed steel M2 on the basis of an internal nitriding zone without a brittle nitride zone. The results of studies of the nitrided steel phase composition with a change of the saturating atmosphere during dilution of ammonia by hydrogen are presented. An increase in the resistance of the nitrided tool when drilling structural steel is shown, which is associated with the dispersion hardening of the internal nitriding zone with tungsten nitrides.
