目的探讨矿物柴油碳烟(MCS)和生物柴油碳烟(BCS)对聚α-烯烃(PAO)和柴油润滑性能的影响。设计/方法/方法由矿物柴油(MDO)和生物柴油(BDO)自然燃烧制备两种碳烟。在高频往复试验台上进行了摩擦学试验。用三维激光扫描共聚焦显微镜和拉曼光谱对摩擦表面进行了表征。结果在大多数情况下，在PAO中加入MCS和BCS可以减少摩擦。当MCS含量不超过1.0%时，MCS对磨损量的影响可以忽略不计。相比之下，即使在低含量时，BCS对耐磨性也有很大的负面影响。对于柴油，MCS降低了摩擦和磨损，而BCS显著恶化了BDO的润滑。MCS在摩擦表面形成了Fe3O4/C复合润滑膜。BCS也进入了接触区，但没有形成有效的Fe3O4/C复合润滑膜。原创性/价值这项工作从不同的角度比较了MDO和BDO，即它们燃烧的碳烟对润滑油和燃料油润滑的影响。BCS对润滑油和BDO的润滑有明显的负面影响，这是BDO在工业应用中可能出现的问题。
Purpose This paper aims to explore the effects of mineral diesel fuel carbon soot (MCS) and biodiesel carbon soot (BCS) on the lubrication of polyalphaolefin (PAO) and diesel fuels. Design/methodology/approach Two styles of carbon soot were prepared from the natural combustion of mineral diesel fuel oil (MDO) and biodiesel oil (BDO). Tribological tests were conducted on a high-frequency reciprocating rig. Friction surfaces were characterized using three-dimensional laser scanning confocal microscopy and Raman spectroscopy. Findings The addition of MCS and BCS to PAO could reduce friction in most cases. MCS had a negligible effect on the wear for contents not exceeding 1.0 per cent. By contrast, BCS exhibited a considerable negative influence on the wear resistance even at low contents. For diesel fuels, MCS reduced both friction and wear, whereas BCS substantially deteriorated the lubrication of BDO. MCS formed a Fe3O4/C composite lubricating film on the friction surface. BCS also entered the contact region, but it did not form an effective Fe3O4/C composite lubricating film. Originality/value This work compared MDO and BDO from a different perspective, i.e. the effects of their combustion carbon soot on the lubrication of lubricating oil and fuel oil. The significant negative effect of BCS on the lubrication of lubricating oil and BDO is a problem that could occur in the industrial application of BDO.
