摘要

润滑油在减少许多机械系统的摩擦和磨损方面起着重要作用。传统润滑剂中的添加剂不足以减少当今机械系统的摩擦和磨损。然而，由于这些添加剂的快速化学降解，它们的使用对环境产生了重大影响。近年来，纳米颗粒基润滑剂因其摩擦减量特性而受到广泛关注。因此，研究纳米颗粒在常规润滑剂中的作用及其对机械系统摩擦学特性的影响具有重要意义。因此，本文主要研究了六方氮化硼纳米颗粒纳米流体的制备及其对柴油机缸套和活塞环摩擦学特性的影响。制备了不同浓度的hBN纳米颗粒基纳米流体，并用紫外可见光谱和热重分析对其进行了表征。实验分析结果表明，hBN纳米颗粒作为润滑油添加剂比常规基础油20W40具有更好的抗磨减摩性能。

Examining the role of hexagonal boron nitride nanoparticles as an additive in the lubricating oil and studying its application

Lubricating oil plays an important role in minimizing the friction and wear of many mechanical systems. The additives present in the conventional lubricant are inadequate to reduce the friction and wear of today’s mechanical systems. However, the use of these additives has a significant effect on the environment due to their fast chemical degradation. In recent years, nanoparticle-based lubricant has attracted great attention due to their friction reduction behavior. Therefore, it is of great importance to examine the role of nanoparticle addition in the conventional lubricant and its influence on the tribological characteristics of the mechanical systems. Hence, this research work focused on the formulation of hexagonal boron nitride nanoparticle-based nanofluids and its effect on the tribological characteristics of cylinder liner and piston rings of a realistic diesel engine. The different concentrations of hBN nanoparticle-based nanofluids were formulated and characterized using the ultraviolet–visible spectroscopy and the thermal gravimetric analysis. The results of the experimental analysis showed that hBN nanoparticles as an additive in the lubricating oil exhibited better anti-wear and friction reduction behavior than the conventional base oil 20W40.
