Abstract
This paper presents the results of the obtained carbon nanostructures by the method of arc synthesis in helium. During the synthesis, the methodology for producing fullerene-containing soot was worked out and the yield of fullerenes was increased by 6% at an optimal current of 180 A and a voltage of 30 V, at a vacuum in the reactor of ~ 0.004 Torr, and helium supply of 0.4 kg / cm2, water temperature of the cooling system ~ 19° C, The obtained nanostructures were subjected to purification by evaporation using a Soxhlet apparatus in 5 cycles. Then the obtained fullerenes C60 and C70 were investigated using analytical instruments confirming their presence. After that, the obtained fullerene mixtures were prepared in suspension and tested on a friction and wear machine. During the experiments, the optimal proportions of mixtures of fullerenes with industrial oils I - 40, as well as additives of metal micropowders were selected. The results of the analysis showed that the addition of fillers reduced friction and wear by 3-4%, which improves the effectiveness of additives from previous studies.
