外加电场作用下离子液体在摩擦学性能方面的研究进展
|
摘要
最近几年来,在理论和实验研究方面,因薄膜润滑状态下的城膜特性和摩擦学行为发展迅速,使人们对纳米级润滑薄膜的摩擦学方面有了了解。但对纳米级润化薄膜在电场情况下的成膜特性研究很少,且对部分现象的揭示存在很多没有解决的问题。在理论和实验方面都较为匮乏,因此开展这方面的研究工作迫在眉睫。本文主要对近些年来在通入外加电场后离子液体的摩擦学性能方面的研究进展进行了简单的综述。
In recent years, in terms of theoretical and experimental research, the film properties and tribological behavior under film lubrication state have widely researched, making people understand the tribology of nano-scale lubrication film. However, there are few researches on the film-forming properties of nanoscale films under electric field, and there are many unsolved problems in revealing some phenomena. Both the theoretical and experimental aspects are scarce. Therefore, it is extremely urgent to carry out research on this field. In this article, research progress in the tribological properties of ionic liquids under applied electric field was introduced.
