| 摘 要： | 本文以蓖麻油聚氧乙烯醚水基润滑液为研究对象，分别使用润滑膜厚度测量仪、微摩擦试验机和四球摩擦试验机对其成膜特性、摩擦磨损特性和抗磨极压特性进行了系统的研究，并用扫描电子显微镜和能量色散光谱仪对摩擦磨损机制进行了分析。结果表明：蓖麻油聚氧乙烯醚提高了纯水的成膜能力，能够在钢-铝摩擦副形成有效的润滑膜，起到良好的减摩抗磨效果。随着浓度的增大，对钢-铝摩擦副的减摩抗磨性能和四球摩擦试验的抗磨极压性能都得到了提高。

| Abstract: | The soluble polyether has attracted more attention due to its excellent lubricating performance and environment-friendly properties. The lubricating characteristics of castor oil polyoxyethylene ether solution, e.g. film forming ability, friction-reducing, anti-wear and extreme pressure properties, were systematically investigated on the lubricating film measuring instrument, universal micro-tribotester and four-ball friction tester, respectively. The friction and wear mechanisms were analyzed by scanning electron microscopy and energy dispersive spectroscopy. The results show that the film forming ability of water was improved by mixing in castor oil polyoxyethylene ether. The effective lubricating film can be formed at the tribo-interface of steel/aluminum tribo-pair to reduce friction coefficient and improve anti-wear properties. The performance of the castor oil polyoxyethylene ether solution in friction reduction, anti-wear and extreme pressure was improved with the increasing solution concentration. |
