We report microscale friction experiments for diamond/metal and diamond/silica contacts
under gigapascal contact pressures. Using a new nanoprobe technique that has a sufficient …

Observation of partial interface slip prior to sliding is reported in micrometre-scale single
asperity contacts formed of diamond tips and various substrate materials. Using a dual-axis …

Large-scale molecular-dynamics simulations are performed to study friction in nanoscale
single asperity contacts. The modeling system consists of a tip made of H-terminated …

A micromechanical dislocation model of frictional slip between two asperities is presented.
The model suggests that when the contact radius is smaller than a critical value, the friction …

Atomic force microscopy (AFM) experiments and molecular dynamics (MD) simulations were
conducted to examine single-asperity friction as a function of load, surface orientation, and …

Experiments with a multidimensional nano-contact system have shown that, prior to kinetic
frictional sliding, there is a significant reduction of the tangential contact stiffness relative to …

The high-speed tribological properties of microscale contacts are studied using an indenter
probe and quartz crystal microbalance. Elastic and dissipative shear forces are monitored as …

The most commonly observed friction behavior for sliding systems is that described by
Amontons laws of friction. In this case, sliding friction is independent of the gross or apparent …

In this article, we review the present status of experimental and theoretical work on friction at
the interface between extended macroscopic bodies, rough on the micrometer scale. We …

Friction at the nanoscale differs markedly from that between surfaces of macroscopic extent.
Characteristically, the velocity dependence of friction between apparent solid/solid contacts …
