Abstract

Lubricating greases are widely used in mechanical engineering, especially in rolling bearing. Carbon-based materials show promise as lubricant additive for formulating high-performance grease. However, the enhancement of lubrication performance of carbon-based materials limits by the simple lubricating mechanism. This work demonstrates that nanocomposite of metal–organic frameworks (MOFs)-derived carbon as a grease additive can improve the tribological properties of bentone grease. HKUST-1 was synthesized by a solvent method and converted into HKUST-1derived carbon (HDC) via one-step pyrolysis sacrifice template method. After pyrolysis of HKUST-1 at 350 °C, Cu²⁺ was reduced to zero-valence copper. With increasing pyrolysis temperature from 350 to 950 °C, both the particle size of copper in HDC and the degree of graphite defect increased gradually. Types of HDCs as base grease additives significantly improved friction-reduction and anti-wear performance of bentone grease. Compared with the base grease, HDC-950 °C with the amount of 2 wt% addition reduced friction coefficient and wear volume loss by 35.5% and 97.0%, respectively. The superior tribological performance of the HDC-950 °C is attributed to the synergistic effect of carbon and copper nanoparticles to induce tribochemical reaction, which form a stable protective film on the friction surfaces. This study highlights the potential of MOFs-derived carbon for developing high-performance grease additives.

HKUST-1衍生碳纳米复合材料作为润滑脂添加剂，用于减少摩擦和磨损

润滑脂在机械工程中应用广泛，特别是在滚动轴承中。碳基材料有望作为高性能润滑脂的润滑剂添加剂。然而，碳基材料的润滑机理简单，限制了其润滑性能的提高。本研究证明了金属有机骨架（mfs）衍生碳纳米复合材料作为润滑脂添加剂可以改善膨润土润滑脂的摩擦学性能。采用溶剂法合成HKUST-1，通过一步热解牺牲模板法转化为HKUST-1衍生碳（HDC）。hust -1在350℃下热解后，Cu2+被还原为零价铜。随着热解温度从350℃升高到950℃，HDC中铜的粒径逐渐增大，石墨缺陷程度也逐渐增大。各类HDCs作为基础润滑脂添加剂，显著提高了膨润土润滑脂的减摩抗磨性能。与基础润滑脂相比，添加量为2 wt%的HDC-950℃，摩擦系数和磨损体积损失分别降低了35.5%和97.0%。HDC-950°C材料优异的摩擦学性能是由于碳纳米颗粒和铜纳米颗粒的协同作用引起的摩擦化学反应，在摩擦表面形成稳定的保护膜。这项研究强调了mofs衍生碳在开发高性能润滑脂添加剂方面的潜力。图形抽象
