Abstract
The effect of small additives of fullerene black (from 0.01 to 1 wt %) on the antifriction and anti-wear properties of a steel-steel pair lubricated with I-40A oil under boundary friction is studied. Based on the results of small-angle and wide-angle X-ray scattering it is suggested that more intensive dispersion of fullerene black in oil results in exposure of the crystalline grains of fullerene C60 and graphite.
