Tribological behavior of Si3N4 ceramic/GCr15 steel components under lubrication of graphene was investigated and found that friction reduction and wear resistance of the sliding pairs were improved by 27% and 43%, respectively, after adding 0.075 wt% of graphene into the base oil. Herein, the lubrication mechanism of graphene nanoplates as oil additives was focused on to promote the practical application of graphene in hybrid ceramic bearings industry. In order to investigate the effect of oil film thickness on tribological properties, the viscosity of blended lubricating oil containing different concentration of graphene was measured and the oil film thickness between rubbing surfaces was calculated using a full numerical solution in point contacts. In addition, the rubbing surfaces were analyzed with combination of EDS and Raman technique. The results demonstrated that the viscosity of base oil and oil film thickness increased with addition of graphene. Graphene entered rubbing interface and prevented ceramic/steel pairs from mechanical contact. Lubrication mechanism including interlayer shearing, surface mending and protective film formation contributed to reduce the friction coefficient and worn scar diameter. 相似文献

Due to the global drive towards biodegradable products, trimethylolpropane [2‐ethyl‐2‐(hydroxymethyl)‐1, 3‐propanediol] (TMP) esters based on palm and palm kernel oils were synthesized, their lubrication properties evaluated, and their potential as base stock for biodegradable lubricants assessed. Two types of TMP esters were considered: palm kernel (PKOTE) and palm oil (PPOTE) TMP esters, derived from palm oil and palm kernel methyl esters, respectively. Lubrication properties such as viscosity, viscosity index (VI) and pour point (PP) were determined according to methods of the American Society for Testing and Materials. Wear and friction properties were evaluated using a four‐ball test machine, while oxidative stability was studied with the Penn State Micro‐oxidation thin‐film test. High VI ranges between 170 to 200 were recorded for these base stocks. PP were relatively high, between 4 to —1 °C, but were improved to at least —33 °C in high oleic palm oil TMP esters. The effects of chemical structure and impurities on wear properties and oxidative stability were also studied. The presence of methyl esters was found to improve wear, but hydroxyl groups in mono‐ and diesters had negative effects at high concentrations. Differences in chemical structures of PKOTE and PPOTE were shown to affect friction and wear results. Both base fluids exhibit oxidative stability comparable to other high oleic base fluids. 相似文献

费托合成及煤化工的发展能够有效缓解我国对石油资源的依赖。本文针对低温煤基合成油与传统石油基石脑油、煤油、柴油、润滑油和蜡产品性能进行对比。文章指出与传统石油基产品对比,费托合成油产品具有蜡含量高、无硫、无氮、少芳烃的特性,满足清洁油品的环保要求,同时在高档润滑油基础油和高熔点石蜡等高附加值产品生产方面更具竞争优势。但费托合成油加工的油品普遍存在凝点、冰点、密度等相关关键指标不合格问题,不同油品的生产,均需要通过异构、精制、裂化、重整等技术改善油品的低温流动性,并通过切割、掺炼等工艺改进才能生产符合标准的油品。文章提出结合我国清洁燃料消费及能源结构调整的变化,费托合成工艺和煤制油应发挥高端产品优势,延伸加工产业链,实现粗放型加工向产业链高端迈进。 相似文献
