A Mechanism for Lubrication between Surfaces with Atomic Level Roughness
Abstract
It is proposed that lubricant molecules adsorbed on an interface between two asperities in contact, which is rough on the atomic scale, can switch the interface from the strong to weak pinning regime, resulting in a large reduction in the static friction. This is proposed as a possible mechanism for boundary lubrication. \
