Friction coefficients for cubic boron nitride were determined with the use of hybrid density functional B3LYP calculations. Two cluster models and an infinite periodic model were applied. Various contacts between duplicated surfaces and different sliding paths of the surfaces with respect to each other were taken into consideration, and friction coefficients were derived. The calculations suggest...
The friction coefficient for two hexagonal boron nitride (h-BN) sheets was estimated on the basis of ab initio calculations. Several models, both cluster and periodic one, were applied to describe h-BN and the interactions between its dimers. In all cases, the gauche orientation is favoured, the interaction energies being virtually independent of the size of the model. The friction coefficient values,...
