Main Title: Adhesive contribution to friction
Author(s): Popov, Valentin L.
Type: Article
Language Code: en
Abstract: This paper addresses the question: what is the physical origin of friction in a contact of two amorphos, hard, smooth elastic surfaces (as e.g. DLC coatings). The dissipation channels due to viscoelasticity, plasticity or elastic instabilities are not active in such systems. We show that short range adhesion leads to "adhesion instabilities" which cause energy dissipation similarly to the classic elastic instabilities mechanicsm. We argue that the main governing parameter determining friction in such systems is the "Johnson parameter" introduced 1995 by K.H. Johnson.
