Abstract

Bio-lubricants are biodegradable and non-toxic. Bio-based lubricants are an attractive alternative to conventional mineral oil-based lubricants. This study deals with the tribological investigation of biodegradable nanolubricants which could be applied in machine tool slideways. The nanoparticle used was copper oxide (CuO) and the biodegradable oils used were coconut oil, sesame oil, olive oil, sunflower oil and soybean oil. The nanolubricants were prepared by adding 0.1% wt. of CuO nanoparticles in each biodegradable base oil. Experiments were conducted on a pin on block type reciprocating friction monitor and four ball tester. Friction, stick-slip and wear characteristics were analysed. The test results showed that the addition of CuO nanoparticles in biodegradable oils improve friction reduction and antiwear properties. The mechanism of friction reduction is found to be the formation of tribofilm through deposition of CuO nanoparticles on the wear surfaces. Field testing was conducted for the best nanolubricants.

机床导轨用cuo基可生物降解纳米润滑剂摩擦学性能实验研究

生物润滑剂可生物降解且无毒。生物基润滑剂是传统矿物油基润滑剂的一种有吸引力的替代品。本研究对可应用于机床导轨的生物可降解纳米润滑剂进行了摩擦学研究。使用的纳米颗粒是氧化铜（CuO），使用的可生物降解的油是椰子油、芝麻油、橄榄油、葵花油和大豆油。纳米润滑剂是通过在每种可生物降解的基础油中添加0.1wt%的CuO纳米颗粒来制备的。在销块式往复摩擦监测仪和四球试验机上进行了试验。分析了摩擦、粘滑和磨损特性。试验结果表明，在可生物降解的润滑油中加入纳米CuO可以提高减摩抗磨性能。研究发现，减摩机理是通过在磨损表面沉积CuO纳米颗粒形成摩擦膜。对最佳纳米润滑剂进行了现场测试。
