Abstract

Friction and wear of vast numbers of motion components subjected to varying unlubricated and oil-starved conditions are critical challenges to be addressed. In this work, innovative phenol-formaldehyde resin (PF) composites were formulated by incorporating halloysite nanotubes (HNTs), and their sliding behavior against bearing steel counterparts was systematically investigated using a pin-on-disc tribometer. When sliding takes place under both unlubricated and oil-starved conditions, the PF-based nanocomposites exhibit ultra-low friction and wear. This behavior originates from the formation of multi-layered tribofilms facilitated by synergistic tribo-physical and chemical actions at the sliding interface. Both the Si-Al-based top layer growing at unlubricated interface and the carbon-based top layer growing at oil-starved interface exhibits remarkable solid lubricating performance. This work presents novel design strategies for advanced tribo-composites with varying tribological conditions.

通过高岭土纳米管促进多层摩擦膜的生长，实现了非凡的固体润滑性能

在不同的无润滑和缺油条件下，大量运动部件的摩擦和磨损是需要解决的关键挑战。在这项工作中，通过加入高岭土纳米管（HNTs）来配制创新的酚醛树脂（PF）复合材料，并使用销盘摩擦计系统地研究了它们对轴承钢的滑动行为。当在无润滑和缺油条件下发生滑动时，基于pf的纳米复合材料表现出超低的摩擦和磨损。这种行为源于滑动界面上的摩擦物理和化学协同作用促进了多层摩擦膜的形成。生长在无润滑界面的si - al基顶层和生长在缺油界面的碳基顶层均表现出优异的固体润滑性能。这项工作提出了具有不同摩擦学条件的先进摩擦复合材料的新设计策略。

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.
