纳米和微米tio2颗粒对ptfe/peek复合材料摩擦学性能的影响
DOI: 10.3969/j.issn.1671-7627.2014.06.006, PP. 31-36
Keywords: 聚四氟乙烯/聚醚醚酮复合材料,tio2,摩擦学性能
Abstract:
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。
