不同地域云杉表面蜡质的润滑性能研究
|
摘要
分别采集阿拉善地区的青海云杉和双鸭山地区的青仟云杉,提取叶片表面蜡质并用气质联用(GCMS)对提取的云杉表面蜡质进行成分分析。利用MFT-4000摩擦磨损试验机,以合成酯作基础油,云杉蜡质作为添加剂,研究其在钢-钢和钢-铝摩擦副下的润滑性能,考察云杉蜡质成分作为绿色润滑油添加剂的可能性。用光学显微镜观察钢块和铝块表面磨痕形貌,用飞行质谱仪(SIMS)对磨痕表面成分进行分析。结果表明:两种云杉表面蜡质作为添加剂时均能够起到良好的减摩抗磨作用,其润滑机理是蜡质成分中的极性物质与金属表面分子形成吸附膜或反应膜,从而起到减摩和抗磨作用。
The Qinghai spruce in Alashan area and green thousand spruce in Shuangyashan are collected,respectively.Their leaf-surface wax are extracted and the composition of the leaf-surface wax are analyzed using the gas chromatography and mass spectrometer(GCMS).The tribological behaviors of the steel-steel and steel-aluminum friction pairs under synthetic ester as base oil and leaf-surface wax as the additive are investigated using MFT-4000 friction and wear tester.The possibility of spruce as green lubricant additive is investigated.The wear surface are characterized and analyzed based on optical microscopy and Time of flight mass spectrometer(SIMS).The results show that leaf-surface wax of the two spruce as additives have better friction reducing and wear resistance properties.The lubrication mechanism is wax composition of polar material formed adsorption or reaction films on worn surface,which plays the functions of friction reducing and wear resistance.
