Effect of the electric current on the friction and wear properties of the CNT–Ag–G composites
Feng Yi,Min Zhang,Yi Xu +2 more
TL;DR: In this paper, the friction coefficient, wear volume loss and contact voltage drop of composites with and without current were investigated and worn surface were observed using SEM, and the results showed that the worn surface was larger than that of negative brush due to the forming of continuous lubrication film between brush and ring under mechanical wear.

Thermal deformation in frictionally heated contact
TL;DR: In this paper, the transition from smoothly distributed asperity contact to a condition where the surfaces are supported by a few thermal asperities is discussed, including wear, cooling and hydrodynamic lubrication.
