ПОВЫШЕНИЕ ПРОЧНОСТНЫХ СВОЙСТВ ПОВЕРХНОСТЕЙ СТАЛЬНЫХ ДЕТАЛЕЙ ВАКУУМНЫМ ТЕРМОЦИКЛИЧЕСКИМ АЗОТИРОВАНИЕМ В ПЛАЗМЕ ПУЛЬСИРУЮЩЕГО ТЛЕЮЩЕГО РАЗРЯДА

As a result of the studies, the regularities of the influence of the VTAP1ITR TP parameters on the microhardness, the diffusion saturation depth, the magnitude and distribution of residual stresses in the hardened layers of steel surfaces are established. Based on the use of expert assessment methods and the results of a series of screening experiments, optimization criteria (endurance limit and corrosion resistance) and controlled factors for mathematical modeling of the formation of reinforced ion-nitrated surface layers are determined. A mathematical model of the TP of the formation of reinforced surfaces of the VTAPPTR TP according to the criteria of endurance and corrosion resistance is obtained. An analysis of the studies showed that there are no general conclusions and recommendations on the selection of the optimal technological parameters of the VTAPTTR that would be used for the practical application of this technology. These circumstances confirm the need for further study of the VTAPTTR technology and the expediency of its optimization.
