摘要:
研究不同体积分数纳米和微米TiO2填充聚四氟乙烯/聚醚醚酮(PTFE/PEEK)复合材料的摩擦学性能,考察载荷、滑动速率对复合材料摩擦学性能的影响。结果表明:纳米和微米TiO2均有助于提高PTFE/PEEK复合材料的摩擦学性能,当TiO2体积分数为1%时,TiO2/PTFE/PEEK复合材料具有最佳摩擦学性能。1%纳米TiO2填充PTFE/PEEK复合材料的磨损率仅为PTFE/PEEK复合材料的50%左右和1%微米TiO2/PTFE/PEEK复合材料的70%。此外,在相同的试验条件和填充比例时,纳米TiO2填充PTFE/PEEK复合材料比微米TiO2填充的复合材料表现出更好的减摩、抗磨性能以及更低的接触面温度。扫描电子显微镜照片显示:1%纳米TiO2有助于PTFE/PEEK复合材料形成均匀、光滑的转移膜,并减少PTFE/PEEK复合材料的黏着磨损。
Abstract:
The tribological performance of volume fraction of nano-TiO2 and micro-TiO2 filled polytetrafluoroethylene/polyethertherketone(PTFE/PEEK)composites was studied, and the influences of various loads and sliding speeds on the tribological performance were also investigated.Results showed that nano-TiO2 and micro-TiO2 could improve the tribological performance of PTFE/PEEK composites, thus the best tribological performance was obtained at 1% TiO2. The wear rate of 1% nano-TiO2/PTFE/PEEK composites was only 50% of that of PTFE/PEEK composites and 70% of that of micro-TiO2/PTFE/PEEK composites. In addition,in the same testing conditions and filler contents,the nano-TiO2 filled in PTFE/PEEK composites had better tribological performance and lower contact temperature than that of micro-TiO2/PTFE/PEEK composites.Scanning electron microscope(SEM)images revealed that 1% nano-TiO2 could form uniform, and smooth transfer film, and reduce the adhesive wear of PTFE/PEEK composites.
