采用化学气相渗透与液体熔体渗透相结合的方法制备了C/SiC制动材料。 研究了C/SiC制动材料的磨损机理。 主要磨损机理为晶粒磨损、氧化磨损、疲劳磨损和粘着磨损。这些磨损机制总是同时发生，且相互促进。晶粒磨损主要是硬质SiC晶粒作用的结果。粘着磨损会导致高磨损率和不稳定的摩擦系数。Si是影响粘着磨损的重要因素，因此C/SiC制动材料中的Si必须被删除 皇冠版权所有 (C) 2010 由 Elsevier Ltd 出版 保留所有权利
The C/SiC brake materials were fabricated by chemical vapor infiltration combined with liquid melt infiltration The wear mechanisms of C/SiC brake materials were investigated The main wear mechanisms were grain-abrasion oxidation-abrasion fatigue wear and adhesive wear These wear mechanisms always occurred simultaneously and showed mutual enhancing effects between them Grain-abrasion mainly was the result of hard SiC grain action Adhesive wear could cause high wear rates and a large unstable friction coefficient Si was the significant factor on the adhesive wear so Si in the C/SiC brake materials must be removed Crown Copyright (C) 2010 Published by Elsevier Ltd All rights reserved
