“润滑”之新解

A Novel Insight into “Lubrication”

摘要: 润湿与润滑分别属于两个不同的研究范畴, 但两者之间又有着必然的因果关系。本文简要介绍了表面“润” 与“滑”之间的关系; 并归纳出一般规律, 即, 对于固-固接触摩擦为“润”而“滑”, 而对于固-液接触摩擦为“润”而 “黏”,“去润”而“滑”.

Abstract: Wetting and lubrication belong to two different research areas, but have an inevitable correlation. In this article, we will discuss the general relationship between surface “wetting” and “lubrication” from a novel aspect. It is demonstrated that for solid-solid friction, the surface “wetting” leads to “lubrication”, but for the solid-liquid friction, the surface “de-wetting” leads to “slip”.
