A Novel Insight into “Lubrication”

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”.
