纳米陶瓷添加剂在可生物降解基础油中的抗磨性能研究

以生物降解能力强且综合性能好的菜籽油作为基础油,以极压和抗磨性能较好的纳米材料作为添加剂,采用MS-800型四球磨损试验机对试验油极压特性、抗磨性能和摩擦因数进行了研究,分析不同纳米陶瓷添加量对其性能的影响;通过现有润滑油性能的对比,采用均匀设计安排试验,应用SPSS软件对纳米材料与其他添加剂的配伍性进行了回归分析。结果表明：纳米陶瓷添加剂的加入使菜籽油的摩擦性能显著提高,且加入比例得当能满足润滑油的要求;当纳米陶瓷的添加量（质量分数）为1.5%时,相应的最大无卡咬负荷PB值最高达646.8N,磨斑直径最小达0.59mm,摩擦因数最大可降低27%;纳米陶瓷与其他添加剂的复配以及相互作用可提高菜籽油的极压和抗磨性能。

Study of Anti-wear Properties of Nano Ceramic Additives in Biodegradable Basic Oil

The rape seed oil with high biological degradation and comprehensive performance oil was used as basic oil.As engines need high friction performance and internal combustion,nano ceramics with extreme pressure and anti-wear performance was used as additives.With MS-800 type four-ball wear testing machine,the extreme pressure properties,anti-wear properties and friction coefficient were studied.The influence of different ratios of additives on the properties was analyzed,and the current performance and the existing performance were compared.Besides,with uniform design arrangements for test,the complexity of nano ceramics additive and other additives was analyzed by regression with the SPSS software.The results show that with nano ceramic additives friction performance can be significantly improved and adding proper proportion can meet the requirements of the lubricating oil.When the amount of nano ceramics additive is 1.5%,the corresponding maximal non-seizer load PB is 646.6 N at most,and the wear scar diameter is 0.59 mm at least,the friction coefficient can be reduced by 27% at most;the complexity of nano ceramic additive and other additives,and the interaction between them can improve extreme pressure and anti-wear role of rape seed oil.
