摘要:

采用熔融共混挤出⁃注塑的加工方式制备了聚醚醚酮(PEEK)/氟化石墨复合材料,并采用环⁃块摩擦磨损试验机探究其与304#钢环、45#钢环的摩擦学性能,采用扫描电子显微镜(SEM)对其磨面进行分析,并对相关的摩擦学机理进行了探究。结果表明,PEEK复合材料与304#钢环的摩擦因数随氟化石墨添加量的增大呈现逐渐降低的趋势,而与45#钢环的摩擦因数变化并不明显;当氟化石墨添加量低于10 %时,PEEK复合材料与45#钢环摩擦时展示出更低的摩擦因数;当氟化石墨添加量超过于15 %时,PEEK复合材料与304#钢环展示出更低的摩擦因数;就不同载荷而言,PEEK/氟化石墨复合材料与两种摩擦环在300 N的重载荷下均表现出较差的摩擦学性能,而在100 N的低载荷下表现出较高的摩擦因数,但体积磨损率较低。

Abstract:

Polyether ether ketone (PEEK)/fluorinated graphite composites were prepared through melt blending. Their tribological properties against 304# steel and 45# steel were investigated by using a ring⁃on⁃block friction and wear test machine, their worn scar surfaces were analyzed by SEM, and their tribological mechanism were explored. The results indicated that the friction coefficient between the composites and 304# steel decreased gradually with an increase in the content of fluorinated graphite, whereas the change in friction coefficient with 45# steel was not significant. When the content of fluorinated graphite is lower than 10 wt%, the composites exhibit a lower friction coefficient against 45# steel. When the content of fluorinated graphite is higher than 15 wt%, the composites show a lower friction coefficient against 304# steel. According to different loads, the composites with exhibit poor tribological performance toward two types of friction rings under a load of 300 N. However, composites present a higher friction coefficient but a lower wear rate under a load of 100 N.
