Brief historical background about the unit

The Laboratory of the Physics of Surface Hardening was organized at the suggestion of Academician V.E. Panin in 1989 on the basis of the laboratory of high-strength steels and alloys, which since 1987 was headed by A.V. Kolubaev. During the existence of the LFUP, employees published 5 monographs (co-authored), more than 300 works in peer-reviewed journals and proceedings of scientific conferences, received 3 certificates of authorship and 6 patents for inventions, and was awarded a prize named after Academician V.A. Koptyuga (as part of the team) for the series of works “Physical mesomechanics and new ideas about contact fracture of gradient materials; development of technologies for surface engineering of materials and structures.”

The most important scientific results


1. The influence of ultrasound on the plastic flow and structure formation of metals in the zone of intense frictional contact was studied. It has been shown that the ultrasonic effect used ensures a uniform distribution of vibration velocity amplitudes along the length and width of the welded plates without noticeable attenuation. It was found that ultrasonic exposure leads to a decrease in the average grain size in the aluminum alloy B-1469 and increases the proportion of solid solution grains with a cubic recrystallization texture. The effect of artificial aging in the alloy under the influence of ultrasound has been revealed, which is expressed in the preferential separation of a semi-coherent dispersed phase at the expense of an incoherent one. The discovered effect makes it possible to control the structure formation of ultradisperse materials obtained by severe plastic deformation.

2. Systematic studies of the physical, mechanical and tribotechnical properties of functional materials in various structural states were carried out, which made it possible to establish the general patterns of the formation of the structure of the surface layer during friction. A concept is proposed for the formation of surface friction layers as a result of the localization of external stress and temperature due to the exponential decay of dynamic excitations that arise either as a result of adhesive or stochastic interactions of microinhomogeneities of mating surfaces. The mechanism of formation of microstructure fragments in the surface layer is substantiated.

3. In a one-dimensional macroscopic model based on the particle method, the influence of the thickness of the hard coating and the size of the contact spot on the development of plastic deformation in the material for various sliding speeds was studied. A correlation has been established between the magnitude of plastic deformation at the tribological interface, the thickness of the plasticized layer of material under the coating, and the physical and mechanical properties of the gradient material. A non-stationary temporal and spatial nature of the development of plastic shear has been revealed, caused by the release of heat in the surface layer of the material due to intense plastic deformation during friction with high loads.

4. Macroheterogeneous composite materials based on iron and copper with high electrical conductivity, thermal conductivity, load-bearing capacity and strength have been developed. Studies have been carried out on the deformation and destruction of metal composite materials under conditions of sliding friction with the application of an electric field. The patterns of destruction of the friction surface and changes in the structure of materials in the contact zone at increased current density (more than 100 A/cm2) have been established.
