Abstract
The kinetics of capillary condensation in nanoscopic sliding friction was studied on CrN and diamondlike carbon surfaces with an atomic force microscope. A model was presented which reproduced the measured humidity and velocity dependence of the sliding friction on partially hydrophilic and hydrophobic surfaces. Results indicated that for partially hydrophilic and nanometer-scale rough surfaces friction decreased logarithmically with scan velocity, whereas for partially hydrophobic surfaces nanoscale friction increased with velocity.
