Abstract

The influence of fullerenes’ soot concentration, which added to oil М10г2к on few tribotechnical characteristics «steel-steel» was investigated. It was found, that optimal volume of fullerene soot in the oil was 0,1% of the weight. At this level of concentration can be seen the lowest values of coefficient of friction – 0,045, and intense of linear wearing – 2,7×10-9. Through optical investigation the participation of fullerene soot in surface forming mechanism and saturated with carbon was confirmed, it provided an increase in tribotechnical characteristics of the samples.
