摘要/Abstract

摘要： 通过对聚四氟乙烯（PTFE）/芳纶纤维复合编织衬垫进行氧化铈改性处理，利用自制的关节轴承性能试验机，在摆动频率2.5 Hz、摆角±10°条件下，对氧化铈改性处理自润滑关节轴承的摩擦学性能随连续摆动次数的变化进行了探讨，并采用扫描电镜(SEM)、能谱仪(EDS)和X射线光电子能谱(XPS)观察分析了轴承的成膜及磨损机理。结果表明，氧化铈改性处理使自润滑关节轴承的摩擦学性能得到了提高，尤其对提高其耐磨性及防止轴承温度升高效果显著，其原因在于，经氧化铈改性处理的衬垫，其磨损表面在较短时间内形成均匀稳定的片层状PTFE转移膜，转移膜平整光滑、厚薄均匀且耐磨性好；氧化铈改性处理轴承衬垫仅发生了轻微的粘着磨损和磨粒磨损，而未经改性处理的轴承衬垫则发生了较严重的粘着磨损和磨粒磨损。

Abstract: The performances of liners of hybrid polytetrafluoroethylene (PTFE)/kevlar fabrics are modified by CeO₂. The tribological properties of self-lubricating spherical plain bearings are test on the spherical plain bearing tester under continuous swaying condition with a swaying frequency of 2.5 Hz and a swaying angle of ±10°, and the film-forming and wear mechanism of the bearing are analyzed by observing the worn surfaces with scanning electron microscope (SEM), energy dispersive spectrometer (EDS), and X-ray photoelectron spectroscopy (XPS). The results show that the tribological properties of the bearings modified by CeO₂ are much more improved compared to the unmodified bearings, especially the effects of improving the wear resistance and preventing the temperature from rising are remarkable. The reason is that a relatively stable PTFE transfer film forms in a short time on the worn surface of the liner modified by CeO₂, which has good smoothness, thickness uniformity and wear resistance ability. There are slight adhesive and abrasive wears on the modified bearing liners , but there are serious adhesive and abrasive wears on the unmodified bearing liners.

Key words: mechanics, spherical plain bearing, CeO₂, modification, liner, friction wear, polytetrafluoroethylene transfer film
