摘要

用玻璃纤维（GF）单独填充超高分子量聚乙烯（UHMWPE）可以显著提高其耐磨性，但不能有效降低摩擦系数。为了提高GF/UHMWPE复合材料的摩擦学性能，采用γ-甲基丙烯氧基丙基三甲氧基硅烷（KH570）处理的改性凹凸棒土（mATP）作为填料。研究了mATP质量分数对复合材料性能的影响，并进一步考察了mATP/改性gf /UHMWPE复合材料的性能。表征了复合材料的熔融结晶行为、热膨胀、表面润湿性、硬度和力学性能。采用304不锈钢作为滑动面材料，通过干摩擦和水润滑条件下的销对盘试验以及盘对盘水润滑试验对其摩擦学性能进行了评价。分析了复合材料的磨损表面形貌和磨损机理。结果表明，KH570能有效地修饰ATP和GF。与GF/UHMWPE复合材料相比，mATP/GF/UHMWPE复合材料的力学性能有所提高。最佳的ATP含量降低了干摩擦和水润滑条件下的摩擦系数，提高了耐磨性。添加4 wt% mATP的复合材料性能最佳。GF的进一步改性提高了复合材料的整体性能。

Mechanical and tribological properties of ATP-modified GF/UHMWPE water-lubricated bearing composites

Filling ultra-high molecular weight polyethylene (UHMWPE) with glass fiber (GF) alone can significantly enhance its wear resistance but does not effectively reduce the friction coefficient. To improve the tribological properties of GF/UHMWPE composite, modified attapulgite (mATP), treated with γ-methacryloxypropyl trimethoxysilane (KH570), was used as the filler. The influence of mATP mass fraction on composite properties was investigated, and the performance of the mATP/modified-GF (mGF)/UHMWPE composites was further examined. The composites were characterized for their melting and crystallization behavior, thermal expansion, surface wettability, hardness, and mechanical properties. Their tribological performance was evaluated through pin-on-disk tests under both dry friction and water lubrication conditions, as well as disk-on-disk water lubrication tests, with 304 stainless steel as the material for the sliding counterface. The worn surface morphology and wear mechanisms of the composites were analyzed. The results indicate that KH570 effectively modifies ATP and GF. Compared to GF/UHMWPE composites, mATP/GF/UHMWPE composites exhibit enhanced mechanical properties. An optimal ATP content decreases the friction coefficient under both dry friction and water-lubrication conditions, enhancing wear resistance. Composites with 4 wt% mATP show optimal performance. Further modification of GF enhances the overall performance of the composite material.

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
