“…Gellman et al studied the friction between atomically clean Ni(100) crystals ,, and Pd(100) crystals , using a UHV tribometer (Figure a). In this apparatus, a manipulator makes it possible to position the sample in front of surface characterization instruments as well as in front of another sample, with the possibility to change the relative orientation between the two (Figure b).…”

The tribological study of materials inherently involves the interaction of surface asperities at the micro to nanoscopic length scales. This is the case for large scale engineering applications with sliding contacts, where the real area of contact is made up of small contacting asperities that make up only a fraction of the apparent area of contact. This is why researchers have sought to create idealized experiments of single asperity contacts in the field of nanotribology. At the same time, small scale engineering structures known as micro- and nano-electromechanical systems (MEMS and NEMS) have been developed, where the apparent area of contact approaches the length scale of the asperities, meaning the real area of contact for these devices may be only a few asperities. This is essentially the field of microtribology, where the contact size and/or forces involved have pushed the nature of the interaction between two surfaces towards the regime where the scale of the interaction approaches that of the natural length scale of the features on the surface. This paper provides a review of microtribology with the purpose to understand how tribological processes are different at the smaller length scales compared to macrotribology. Studies of the interfacial phenomena at the macroscopic length scales (e.g., using in situ tribometry) will be discussed and correlated with new findings and methodologies at the micro-length scale.

“…Understanding how modifying surfaces affects their frictional properties places stringent requirements on surface cleanliness. The ability to carry out tribological studies under ultrahigh vacuum [25,26] or carefully controlled liquid conditions [27] has allowed the effect of surface modification on friction to be investigated. Such fundamental studies under well-controlled conditions have demonstrated the central importance of the first monolayer in friction reduction at the solid-solid interface [28][29][30][31][32] and have in some instances provided direct insight into the operation of tribological contacts within space environments.…”

This review summarizes recent advances in the area of tribology and the challenges to achieve a molecular level understanding of friction and wear and makes specific recommendations towards attaining such a fundamental understanding. This document represents the results of a two-day workshop, sponsored by the U.S. National Science Foundation, at which participants were charged with defining the outstanding challenges in obtaining a fundamental understanding of friction and wear, thus assisting the National Science Foundation in the effective allocation of resources to address these challenges.
