摘　　要：通过对纯沥青炭基C/C复合材料、含炭黑沥青炭基C/C复合材料和添加氯化铁的沥青炭基C/C复合材料的载流摩擦磨损实验,发现含炭黑沥青炭基C/C复合材料的摩擦系数和磨损量最大,纯沥青炭基C/C复合材料的摩擦系数和磨损量次之,添加氯化铁的沥青炭基C/C复合材料的摩擦系数和磨损量最小,并对3种沥青炭基C/C复合材料的摩擦磨损机理进行了讨论。The wear resistances under electricity for pitch-based C/C composites,pitch-based C/C composites containing carbon black and pitch-based C/C composites with an additive of ferric chloride have been studied.It is found that pitch-based C/C composites containing carbon black possess the largest friction coefficient and wear extent,however the pitch-based C/C composites with an additive of ferric chloride show the smallest values in the three composites.While the friction coefficient and the wear extent of the pitch-based C/C composites is in the middle.Wear mechanism of these three kinds of C/C composites is discussed.
