Directions of activities
Solving the problems of improving the performance characteristics of metal, polymer, composite coatings formed by gas-thermal methods made of powder and wire materials by using rational methods of activating spraying processes, subsequent modification of sprayed layers, identifying patterns of coating formation, their structure, physico-mechanical and operational properties that meet the operating conditions of most friction units of mobile machines and technological equipment.
DEVELOPED AND BEING DEVELOPED:
- theoretical foundations of activated gas-thermal spraying of powder, wire and combined materials in order to increase the reliability of the working surfaces of components operating in extreme conditions
- theoretical foundations of optimal control of non-stationary temperature conditions for obtaining powder coatings by the centrifugal induction method
- a method for calculating the temperature of the layer during induction surfacing, taking into account the influence of joint convective-radiant heat transfer, the properties of the workpiece material, its dimensions and the frequency of the high-frequency current generator used
- theory of sedimentation of nanoscale fillers during centrifugal surfacing of composite coatings
- the concept of a scientifically based choice of a rational method and modes of restoration, hardening and protection of a component is proposed, based on its consideration as an element of a dynamic system, calculated on reliability. Engineering methods are developed for calculating the necessary and sufficient adhesion of coatings applied to tribo-coupling components
- general principles of activating the processes of formation of high-density flame and metallization coatings by satellite streams are proposed and substantiated, which make it possible to provide qualitatively new service characteristics of surface layers
- a new promising approach to the design of technologies for the formation of wear-resistant and antifriction coatings on the components of sliding friction units is proposed by creating and purposefully controlling the use of deformation phase-structural transformations and metastable states that provide a comprehensive improvement of physical, mechanical and operational properties during product operation
- technological processes and equipment for activated flame spraying and hypersonic metallization of wear-resistant, corrosion-resistant, antifriction coatings made of powder and wire materials on wear-resistant structural elements and components of transport vehicles, technological equipment, agricultural machinery with an increase in their service life by 1.4–8 times
- technological recommendations for the production of composite coatings of the “metal – carbide”, “metal – ceramic”, “polymer – metal – ceramic”, and “metal – polymer” systems. Technological recommendations for obtaining layered composite coatings for tribotechnical purposes are developed
- technological bases of manufacturing bimetallic parts of friction units of machines and mechanisms by induction surfacing with the introduction of nano- and micro-dimensional modifiers in copper-based alloys
