摘要：
We propose a model of graphite boundary friction in the presence of adsorbed molecules. We obtain an analytic expression for the specific adhesion τ0 that makes it possible to calculate the friction coefficient with the aid of the known heat of adsorption in a micropore and the magnitude of the crystallite dimension that is characteristic for the given material. On the basis of this model it is possible to explain the increase of the friction coefficient of graphite with increase of the magnitude of the adsorption and evaluate the friction coefficient in the dry friction regime.
