Abstract

To compare them with PTFE-40# steel tribo-pairs, the tribological properties of textured PEEK-40# (AISI 1040) steel friction pairs were researched under full-film lubrication conditions by manufacturing micro-dimples with different dimensions on the contact surfaces of 1040 steel discs using laser surface texturing (LST). After repeated tribological tests, the coefficients of friction (COFs), wear losses, and wear morphologies of the PEEK-1040 steel friction pairs were measured and analyzed. The results show that micro-dimples do not significantly reduce the average COFs of PEEK-1040 steel friction pairs when lubricated with a sufficient amount of hydraulic oil, but they do reduce the wear losses of most groups. When the dimple diameter was 250 μm, the dimple depth was 5 μm, the area ratio was 6.6%, and the mass loss of the 1040 steel disc was reduced by 90% compared to the smooth reference. In comparison to the behavior of the PTFE-1040 steel tribo-pairs, PEEK-1040 steel friction pairs can provide better tribological performance, whether smooth or dimple-textured. This study offers important insights for the design of seals in machinery.

激光微织构PEEK-1040钢摩擦副的摩擦学性能。

为了与PTFE-40#钢摩擦副进行比较，在全膜润滑条件下，采用激光表面织构（LST）技术在1040钢摩擦盘的接触面制造不同尺寸的微窝，研究了织构PEEK-40# （AISI 1040）钢摩擦副的摩擦学性能。通过多次摩擦学试验，对PEEK-1040钢摩擦副的摩擦系数、磨损损失和磨损形貌进行了测量和分析。结果表明：当液压油量足够时，微窝不会显著降低PEEK-1040钢摩擦副的平均COFs，但会降低大多数组的磨损损失；当凹痕直径为250 μm，凹痕深度为5 μm，面积比为6.6%时，1040钢圆盘的质量损失比光滑参比降低了90%。与PTFE-1040钢摩擦副的行为相比，PEEK-1040钢摩擦副可以提供更好的摩擦学性能，无论是光滑还是韧窝纹理。这项研究为机械密封的设计提供了重要的见解。

期刊介绍： Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
