Main directions for research on the development of tribotechnical composites used in the Arctic regions (On the experience of North-Eastern Federal University in Yakutsk)

Abstract

Material science studies the relationship between materials structure and properties and its changes under external influence, and belongs to the priority domains of science and technology. The creation of new materials and also its performance improvement, efficient technologies for their processing is the main goal of material science. Today a substantial number of new metal alloys with special properties, different composites, ceramics, polymers, nanostructured functional powder and synthetic superhard materials, multifunctional coatings, etc. have been designed for various economic activities. But the creation of materials and technologies remains an urgent need, because of the progressive development of manufacturing which requires adaptive materials properties and technologies for their processing. This review analyzesAmmosovNorth-EasternFederalUniversity research directions in the field of tribotechnical materials for use in the Arctic regions. Main areas of research are identified, such as developing of polymer composite materials (PCM) production and improving their performance properties. The prospects of physical processing and chemical modification of the polymer matrix surface are shown. Physicomechanical and tribotechnical properties of antifrictional PCM are discussed. The results of the main theoretical generalizations in the field of analysis of PСM supramolecular structures are presented: 1) effects of critical filler concentrations on the structure and properties of PCM; 2) hypothesis of the nature of intermolecular interaction between the filler and the polymer. The modern tendencies of scientific investigation are shown, namely tribooxidative processes in PCM. The specific development of scientific knowledge and the use of polymers for the northern regions are revealed.
