| 摘 要： | 采用销-盘试验,在转速为60 r/min,法向为载荷(392±29)N,聚合物盘与钢销摩擦副接触形式为面-面,试验时间为1.5 h,试验环境温度为20℃,相对湿度为60%的条件下,研究了200万、300万、500万和900万分子量的UHMWPE分别与钢配副干摩擦时UHMWPE分子量对其摩擦磨损性能的影响,并利用扫描电子显微镜观察其磨损表面形貌。结果表明:UHMWPE分子量其摩擦磨损性能有显著影响,UHMWPE的分子量为300万时,摩擦副的摩擦因数及UHMWPE自身的磨损为最小。

| Abstract: | Friction and wear behaviors of UHMWPE with a molecular weight of 2 million,3 million,5 million and 9 million were investigated respectively against steel at 60 % RH(relative humidity) and 20 ℃ with a pin-disc tribometer under dry friction.The contact between polymer discs and steel pins rubbing pairs took the form of plane/plane with normal load of(392±29) N,rotational speed of 60 r/min and testing time of 1.5 h.In order to investigate wear mechanism,photographies of worn surfaces were observed by SEM.The results showed that influences of molecular weight were obvious on friction and wear characteristics of UHMWPE.It was further demonstrated that the lowest friction coefficient of rubbing pair and the minimum wear of UHMWPE itself appeared in the case of 3 million. |
