Abstract
This article concentrates on the jerkytype phenomenon of surfaces in relative motion (i.e., abreakdown of the Coulomb friction law) in nanocomposite materials. Physical arguments are provided to understand the dependence of friction on sliding velocity in the sense of self-lubrication. Also described is the influence of water vapor adsorption from the testing environment. From a structural design viewpoint, nanocomposite coatings exhibit an optimized combination of functionalities when the nanoparticle becomes of approximately the same size as the separation.
