Tribology on the small scale : a bottom up approach to friction, lubrication, and wear

C. Mathew Mate (Author)
Friction, lubrication, adhesion, and wear are prevalent physical phenomena in everyday life and in many key technologies. This book explains how these tribological phenomena originate from atomistic and microscale physical phenomena and shows how this understanding can be used to solve macroscale tribology problems
