Compared with the graphite, the coefficients of friction of the RL-C/C are lower under the same load of about 0.08-0.12, and the increasing range of the volume losses are still lower than those of the graphite. Compared with the SL pyrocarbon material, the COF and the volume loss of the SL-C/C are about 0.02-0.05 and 0.2 mm^3, lower than those under the same load. The COFs of most RL-C/C and SL-C/C specimens remain stable or decrease slightly with time, while those of the graphite and pyrocarbon specimens increase. The thickness of the integrated friction film of the RL-C/C decreases with load, but the wear surface of the SL-C/C is rough. Tough the wear surface of the graphite is integrated, the serious abrasive wear make the debris move easily and accumulate on the edge of the wear trace to form a restacked morphology. On the wear surface of the pyrocarbon material, some loosed debris, circular worn holes and flake worn out pyrocarbon has been found.
