The purpose of the project - the development of methods and technologies for diffusion welding (DS), soldering and hardening contact surfaces of machine parts with controlled stress-strain state of dissimilar materials to provide energy-saving, high efficiency and productivity of production. When the project used modern methods of theoretical and experimental studies using the material and technical base of the NAA, in particular, electron and light metallography, X-ray microanalysis. To investigate the thermal activation surface of the heat-resistant nickel alloys in the work created a special LED device with a quantitative assessment of the degree of activation. The method of determination of FMS material under DS and soldering required to simulate VAT and absent in the literature. For control measurements used only Ukrainian research station Gleeble 3800 PWI. EO Paton. There's also investigated the structure of compounds with an increase to 50,000 by JEM-120 with an accelerating voltage of 120 kV, the activation of heat-resistant nickel alloy surfaces were performed using compression plasma flows in the Belarusian State University. Computer modeling of the VAT performed by finite element method based on instantaneous deformation, creep and structural transformations. Research and thermal-thermodynamic processes were carried out with regard to their relationship with the VAT and its constituent components, structure and properties of the compounds. Development of wear-resistant materials was carried out taking into account the impact of their structure on the wear resistance and resistance to SSC. Project results provide scientific foundations of ERA Technology, brazing and welding wear-resistant materials in the manufacture of marine gas turbine of new generation plants, promote the use of new materials and improving the efficiency of turbine missile and special equipment. For example, thermal deformation basics of soldering metal-nodes can be developed for soldering metalografitovih units and structures. They can be found in the introduction of other industries. Developments are supported leaves - Support of potential customers: - PWI.
