The conditions for increasing the efficiency of using the technical capabilities of glow discharge plasma generators, depending on the level of their automation, are considered. A dependence with a variable share of costs in the form of automation parameters and rationality is obtained, which allows us to evaluate the operating conditions of an automated system for pumping sets of combined-cycle gas media with reference to automation conditions. The ratio of downtime associated with failures in the automated system of pumping combined-cycle gas media to the corresponding planned indicators is a simple and convenient indicator for assessing the optimality of the conditions for stabilizing the occurrence of downtime and vehicle shutdowns. An algorithm for solving the problem of forming a minimum nomenclature of sets of steam-gas media and the selection of their chemical compositions for technological transitions when processing tools of complex shape and consisting of working parts of different materials is proposed.

The conditions for the hardening of tools in accordance with the author’s technological routes in the optimal time interval are considered using the functional dependence of the serviceability of plasma generators. This dependence takes into account the workability of the technical devices involved in processing the laying batch of tools in the speci ed time interval. The probability of performing the production process in the estimated time is represented by the product of the trouble-free operation of each glow discharge plasma generator involved in the nishing processing of tools that require a different type of plasma exposure in a certain sequence and duration.

A theory has been developed that explains the structure formation in a thin surface layer of a material after low-energy exposure to a glow discharge plasma. This makes it possible to design new methods, technologies and automated devices for the development of an automated technological environment for strengthening various types of tools from various materials. Based on the developed theory, a self-learning system with a developing database was created for monitoring all stages of processing in a glow discharge plasma generator. Any crystal structure can be classified as a complex nonlinear system. When studying the dynamic response of such systems to an external low-energy effect, it was shown that by the time when the nonlinear vibrations stop, the atoms of the crystal lattice are stabilized in new positions. Based on the purpose of the products to be processed in the glow discharge plasma generator, with taking into account their operating conditions, it is possible to increase their production life up to 2 times or more. These technologies should be used at the final stage of the production process because they do not lead to distortion of the shape and size of the working surfaces of products being manufactured. In this case, the residual stresses are redistributed in the surface layer of the material with the formation of an equal structure that improves the running-in conditions of mating parts of devices and mechanisms. For cutting and forming tools, the run-in stage is reduced to the stage of uniform wear.
