The development of complex mechanical systems in present-day conditions has resulted in strengthening the requirements for quality, reliability, and durability of their operation. There is a wide range of measures for meeting these requirements [1]. The relevant objectives of this problem include the development of a scientifically based methodology for manufacturing and technical condition assessment of the mechanical system and its components, providing the necessary and, if possible, sufficient list of technical characteristics and methods for their determination. These problems can be solved using computer programs that enable the simulation of the manufacturing processes of both the mechanical system and its components. Mechanical systems, such as thermal steam and gas turbo-machines, operate effectively only at high speeds and high steam and gas temperatures. That is why, in practice, their rational design has been made possible only after solving a number of significant problems in the field of thermodynamics, aerodynamics, material resistance, and metallurgy. In order to use new heat-resistant materials, including high-temperature ceramic, in the turbine manufacture, complex design and process tasks have to be solved [2]. One of them is to produce a one-piece metal-ceramic unit that meets all the requirements for a gas turbine as an object of a complex mechanical system. Diffusion welding is the most rational method for production such metal-ceramic unit [3, 4, 5].
Despite the obvious significant progress in the diffusion welding technology, there are still many open questions that are difficult, and in some cases impossible, to solve using traditional patterns and approaches. For example, this applies to the material assembling, when the impact of temperatures of more than 0.7 Mp (melting point) and welding pressures above 0.8 yield point (St) leads to irreversible changes in the initial properties of the welded materials or their destruction. Therefore, the main areas of research in the field of technology development is the search for methods to intensify the process of diffusion welding, which would enable to obtain high-quality welded joints at (0.2… 0.3) Mp and welding pressures excluding macro-inelastic deformation of the near-contact zone [6].
