在M-2000型摩擦磨损实验机上,对3种C/C复合材料与40Cr钢配副分别在干态、水润滑、油润滑3种条件下的摩擦磨损行为进行了研究.结果表明:在3种润滑条件下,干态摩擦试样的摩擦系数最大,体积磨损最小;基体炭为树脂浸渍炭的试样在3种试样摩擦系数最高,约为0.141～0.205;水润滑时试样的摩擦系数最小,为0.05～0.10,但体积磨损最大,最高可达7.75 mm3油润滑时试样的摩擦系数和体积磨损均介于干态和水润滑之间;干摩擦时,试样的摩擦系数随着载荷增加而缓慢降低,水润滑和油润滑的摩擦系数则随着载荷的增加而先增加后减少;干态摩擦时材料表面形成了完整的摩擦膜,水润滑和油润滑条件下摩擦膜很薄且不完整;所有润滑条件下试样均以磨粒磨损或犁削磨损为主.
