摘要

Ultra-low friction coefficient was obtained by sliding SFGD/SFGD pair in presence of pure deuterated glycerol and D_2O. The induction period was very short for SFGD material showing the rapid hydrogenation/hydroxylation reactions of its top surface. When surface roughness is very low like in the case of nano-smooth fine-grained diamond coatings, friction behaviour is principally dictated by tribochemical reactions and superlow friction is obtained in presence of H_2 or D_2.
