Friction of diamond graphite and carbon and the
Carbon and graphite have a negative tem perature coefficient of friction. The low friction normally observed with diamond is due to the presence of adsorbed oxygen and other gases. The friction of clean diamond on diamond is high and the shear strength at the interface is comparable with the shear strength of diamond.
