摘要
采用化学气相浸渗(CVI)与聚合物浸渍裂解法(PIP)相结合的工艺制备碳/碳(C/C)复合材料,利用CFT-I型材料表面性能综合试验仪对C/C复合材料进行往复摩擦磨损测试,采用扫描电镜对C/C复合材料的微观组织与摩擦磨损试验后的表面形貌进行表征,研究了沉积温度对CVI+PIP工艺C/C复合材料微观组织与摩擦磨损性能的影响规律。结果表明:与石墨材料相比,C/C复合材料具有更加理想的摩擦磨损性能;沉积温度为1050℃制得的C/C复合材料具有稳定的摩擦系数和最低的磨损率,在该温度下产生的孔洞和裂纹极少,浸渗效果最为理想。
A combination of chemical vapor infiltration(CVI)and polymer impregnation pyrolysis(PIP)was used to prepare carbon/carbon(C/C)composites.CFT-I comprehensive material surface property tester was used to perform reciprocal friction wear test on the C/C composite.Scanning electron microscope was used to characterize the microstructure and post-friction surface morphology of C/C composites.The effect of deposition temperature on the microstructure and friction/wear properties of C/C composites prepared by CVI+PIP processes was investigated.The results show that C/C composites present more desirable friction wear performance compared with graphite materials.The C/C composite with very few holes and cracks at the deposition temperature of 1050℃show a stable friction coefficient and the lowest wear rate,and the frictional wear performance is ideal.The infiltration effect is the best.
