摘要

六方氮化硼因其结构、物理和化学特性而被视为润滑脂的添加剂。在实际摩擦学系统中应用此类润滑剂时,重要的是要认识到六方氮化硼不仅对摩擦学特性有影响,而且对这类润滑剂的其他功能特性也有影响。本研究进行了滴点、渗透和机械稳定性等测试。此外,研究还特别关注添加剂本身的特性,包括粒度分布和吸附特性(通过扫描电子显微镜和低温吸附等温线确定)。在锂基润滑脂和钙基润滑脂中加入六方氮化硼颗粒后,增强了对高温和长时间机械应力的抵抗能力。这一现象归因于基础润滑脂的类型以及加入固体颗粒后润滑脂空间网络结构的改变。研究发现,粒径更小、纳米颗粒成分占很大比例、多孔结构更发达的添加剂更有效。对润滑脂结构的显微观察证实,固体颗粒沉积在润滑脂的空间网络中。研究发现,六方氮化硼在润滑脂结构中的分布取决于添加剂的物理和化学特性。此外,基础润滑脂的类型(包括皂纤维网的排列)也是一个影响因素。

Effect of Nanoparticles and Microparticles of Hexagonal Boron Nitride on Structure, Thermal and Mechanical Stability of Lithium and Calcium Greases

Hexagonal boron nitride is being considered as an additive for greases due to its structure and physical and chemical properties. In the context of the application of such lubricants in real tribological systems, it is important to recognise the effect of hexagonal boron nitride not only on tribological properties, but also on other functional properties of this group of lubricants. In the present study, tests including dropping point, penetration and mechanical stability were carried out. Additionally, particular focus was placed on the properties of the additive itself, including particle size distribution and adsorption properties, as determined by scanning electron microscopy and low-temperature adsorption isotherms. The introduction of hexagonal boron nitride particles into lithium and calcium greases resulted in enhanced resistance to high temperature and prolonged mechanical stress. This phenomenon was attributed to the type of base grease and the modifications in the configuration of the grease's spatial network that ensued as a result of the incorporation of solid particles. It was found that an additive with a smaller particle size and a significant proportion of nanoparticle fractions, and a more developed porous structure, was more effective. Microscopic observations of the structure of the greases confirmed that the solid particles were deposited in the spatial network of the greases. The distribution of hexagonal boron nitride in the grease structure was found to be contingent upon the physical and chemical properties of the additive. Furthermore, the type of base grease, including the arrangement of the soap fibre network, was identified as a contributing factor.
