采用MM-1000型摩擦磨损试验机测试了粗糙层基体炭C/C复合材料试样在不同制动速度下的摩擦磨损性能,借助微区拉曼光谱和扫描电镜研究了试样摩擦面的结构与形貌.结果表明粗糙层基体炭C/C复合材料具有优异的摩擦速度特性.试样的摩擦系数和试验后摩擦面上碳原子的有序度无直接对应关系,制动速度对摩擦系数的影响应归因于制动速度对摩擦面温升和摩擦膜厚度及完整性的影响.5 m/s的低制动速度下,试样因吸附水气摩擦系数持续低值(0.15),摩擦面上无连续摩擦膜产生;10 m/s的制动速度下水气被解吸附,摩擦面出现多层厚膜,摩擦系数达到峰值(0.5),此后,随制动速度增加,摩擦膜减薄,材料磨损量呈下降趋势;当制动速度增加到25 m/s及以上,摩擦面的温升导致氧化质量损失和线磨损增加,摩擦系数也稍有衰减(0.3).
