Abstract

Our experiments aimed to study the influence of layered materials with nanometric-scale particles, which are part of lubricant oils, on their tribological properties. The object of this study was a lubricant oil made using base oil PAO4, which contained nanoparticle hexagonal boron nitride (nano h-BN) and a dispersant based on succinic acid imide. Comparative tests for engine oil (CB30) were also performed. The paper presents the method of preparing the test material and the tribological test results, including wear spot diameter (wear mark), limit wear load, and seizure load. The test results obtained demonstrate that nano-hexagonal boron nitride improves the tribological properties of lubricant oils. However, oil preparation and the quantitative selection of components markedly influence the results.

摘要

我们的实验旨在研究作为润滑油一部分的具有纳米级颗粒的层状材料对其摩擦学性能的影响。本研究的对象是一种使用基础油PAO4制成的润滑油，其中含有纳米颗粒六方氮化硼（纳米h-BN）和一种基于琥珀酸亚胺的分散剂。还对发动机油（CB30）进行了对比测试。本文介绍了测试材料的制备方法以及摩擦学测试结果，包括磨损斑直径（磨损痕迹）、极限磨损载荷和咬死载荷。所获得的测试结果表明，纳米六方氮化硼改善了润滑油的摩擦学性能。然而，油的制备和成分的定量选择对结果有显著影响。
