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.

Wear and corrosion involve mechanical and electrochemical mechanisms, and the combined action of these mechanisms often result in significant mutual reinforcement. To measure the effect on wear-corrosion resistance of the chemical and abrasion wear separately at the same time, wear-corrosion synergism rate is selected to indicate the nature and degree of the chemical and abrasion wear.

腐蚀磨损是同时涉及力学因素和电化学因素的复杂的材料的流失过程，通常条件下，腐蚀磨损不是纯磨损和纯腐蚀的简单叠加，还有两者间的协同作用，为定量描述腐蚀与磨损的促进程度、进一步完善腐蚀磨损机理，本文利用腐蚀磨损协同作用率值的大小来分析腐蚀和磨损的交互作用程度，结果表明：本文制备的镀层，在5％H_2SO_4溶液中腐蚀磨损时，机械磨损是造成镀层表面材料流失的主要原因，腐蚀和磨损的协同作用为次要因素。
