Abstract
⺠Uses first-principle quantum calculations in the form of density functional theory (DFT) to compute the pressure-dependent shear strength of a model KCl tribofilm. ⺠Shows that first principles quantum theory can reproduce the experimentally measure value of the zero-pressure limit of shear strength. ⺠Analyses the origin of pressure-dependent shear strengths in boundary lubrication. ⺠Demonstrates that the difference between the experimental and theoretical values of the proportionality constant between shear strength and pressure cannot be accounted for by differences in film thickness.
