Abstract

In this research, nanocomposite carbon has been found to have excellent tribological properties as a lubricant additive. To reduce high friction and wear in friction pairs, the modified nanocomposite carbon has been prepared for chemical technology. The morphology and microstructure of the modified nanocomposite carbon were investigated via TEM, SEM, EDS, XPS, and Raman. In this study, varying concentrations (1, 3, and 5 wt. %) within the modified nanocomposite carbon were dispersed at 350 SN lubricant for base oil. The suspension stability of lubricating oils with the modified nanocomposite carbon was determined by ultraviolet-visible light (UV-VIS) spectrophotometry. The friction and wear characteristics of lubricants containing materials of the modified nanocomposite carbon were evaluated under reciprocating test conditions to simulate contact. The morphology and microstructure of the friction pair tribofilms produced during frictional contact were investigated via SEM, EDS, and a 3D surface profiler. The results showed that scratches, pits, grooves, and adhesive wear were significantly reduced on the surface of the friction pair which was used with 3% nanocomposite carbon lubricant. Additionally, the modified nanocomposite carbon showed excellent friction reducing and anti-wear performance, with great potential for the application of anti-wear.

摘要

在本研究中，已发现纳米复合碳作为润滑剂添加剂具有优异的摩擦学性能。为降低摩擦副中的高摩擦和磨损，已制备出用于化学工艺的改性纳米复合碳。通过透射电子显微镜（TEM）、扫描电子显微镜（SEM）、能谱仪（EDS）、X射线光电子能谱（XPS）和拉曼光谱对改性纳米复合碳的形态和微观结构进行了研究。在本研究中，将不同浓度（1%、3%和5%重量比）的改性纳米复合碳分散在350 SN基础油中作为基础油。用紫外可见分光光度法（UV-VIS）测定了含有改性纳米复合碳的润滑油的悬浮稳定性。在往复试验条件下模拟接触，评估了含有改性纳米复合碳材料的润滑剂的摩擦和磨损特性。通过扫描电子显微镜（SEM）、能谱仪（EDS）和三维表面轮廓仪研究了摩擦接触过程中产生的摩擦副摩擦膜的形态和微观结构。结果表明，与3%纳米复合碳润滑剂一起使用的摩擦副表面的划痕、凹坑、沟槽和粘着磨损显著减少。此外，改性纳米复合碳表现出优异的减摩和抗磨性能，具有很大的抗磨应用潜力。
