“…The effect of the filler on the property of the composition depends on the size of its grains, the concentration in the system and the chemical nature of the polymer matrix. Due to the high surface energy of fillers, their introduction into the polymer matrix improves adhesion properties and resistance to operational loads [8][9][10][11][12][13]. In the paper [14,15] it is noted that the peculiarity of modification of polymer materials by nanoparticles is the increase polymer matrix adhesion to the surface of nanoparticles, uniform distribution of nanoparticles along the matrix volume and ultra small concentrations of modifiers.…”

The operation of modern machines and equipment is impossible without technical service, which accounts for up to 35% of the total structure of operating costs. Therefore, ensuring timely maintenance with minimal downtime at the lowest cost is a vital task. One of the resource-defining elements of machines is bearing units, and increasing their durability is a promising direction. The analysis of defects occurring in bearing units showed that the main cause of surfaces wear under rolling bearings is fretting corrosion which occurs due to the impossibility to have an effective contact spot with an area of more than 35... 40% in cylindrical joints. There are many ways to restore parts, but due to the high competitive capabilities polymeric compounds methods are widely used. Such materials allow quick repair, they also increase the resource of individual nodes and, as a consequence, the entire renovation object as a whole. Due to their performance characteristics, polymers have been widely used both in manufacturing and in renovation of parts and units operating under severe dynamic loads and aggressive environments. However, they have insufficient resistance to vibration loads and aggressive working fluids. The solution to this problem is the development of new polymer nanocompositions based on anaerobic compositions using dispersed nanofillers. Due to the high surface energy of nanoparticles their introduction into the polymer matrix will increase adhesion strength, resistance to vibration and impact of working fluids.
