中文摘要:
      目的 设计三维网状石墨烯(3D framework carbon, 3DFC)作为PAO-6基础油添加剂,改善基础油的摩擦磨损性能,提高基础油的抗断油能力。方法 使用十八胺修饰得到亲油的3DFCs,将0.001 g 3DFCs粉末添加到10 g PAO基础油中,超声分散30 min,得到稳定分散的3DFCs润滑油。利用场发射扫描电子显微镜(FESEM)、透射电子显微镜(TEM)、能量分散X射线仪(EDX)、傅里叶变换红外光谱仪(FTIR)和拉曼光谱仪(Raman)分析了3DFCs的微观形貌和结构。利用CSM摩擦试验仪器评估了3DFCs作为基础油添加剂的摩擦学性能,并用扫描电镜、拉曼光谱对磨斑及磨痕成分进行了分析。结果 经十八胺修饰的3DFCs的亲油性得到提高,可在PAO-6基础油中稳定分散。3DFCs作为PAO-6基础油添加剂(0.01%),在非断油摩擦情况下,其磨损率较PAO-6基础油降低了约1个数量级,而较0W-50机油并未降低。在断油摩擦情况下,PAO-6基础油和0W-50机油易发生摩擦失效,3DFCs润滑油能保持平稳有效摩擦,其抗断油性能最优。结论 具有三维结构、石墨层间距大、润滑性能优异的3DFCs作为润滑油添加剂,具有良好的抗断油能力,可以有效地保护摩擦部件免遭损坏。
英文摘要:
      The work aims to design a three-dimensional network of carbon (called as 3D framework carbon, 3DFC) as PAO-6 base oil additive to improve the tribological properties and anti-interrupting-oil ability of the base oil. Octadecylamine was used to get oleophilic 3DFCs and 0.001 g 3DFCs powder was added to 10 g PAO base oil to obtain stable and dispersed 3DFCs lubricating oil by ultrasonic dispersion for 30 min. The microstructure and morphology of 3DFCs was analyzed by scanning electron microscopy (FESEM), transmission electron microscopy (TEM), energy dispersive X-ray (EDX), fourier transform infrared (FTIR) and Raman spectroscopy. The tribological properties of 3DFCs as base oil additive were evaluated by CSM tribometer. The wear spots and scars were characterized by SEM, EDX and Raman spectroscopy. The 3DFCs modified by octadecylamine had higher lipophilicity and could be dispersed steadily in PAO-6 base oil. As PAO-6 base oil additive (0.01wt.%), the wear rate of 3DFCs decreased by an order of magnitude compared with the pure PAO-6 under non anti-interrupting-oil friction test, and but did not fall compared with the 0W-50 engine oil. PAO-6 base oil and 0W-50 engine oil had frictional failure in the anti-interrupting-oil friction test. 3DFCs lubricating oil could maintain smooth and effective friction and its anti-interrupting-oil ability was the best. 3DFCs with advantages of three-dimensional structure, large graphite layer spacing and excellent lubricating properties as additives can significantly improve anti-interrupting-oil ability of PAO-6 base oils and protect friction parts from damage.
