Soft Interfaces, Quasicrystals and Tribology

Abstract

An analytical model for dry friction using a combination of dislocation drag and solid-solid interface theory was developed. This model, with no adjustable parameters, gives semi-quantitatively correct numbers for experimental friction coefficients in ultra-high vacuum, and is also consistent with a number of other experimental finding ranging from the formation of contact layers to temperature dependence. Experiments on macroscopic single crystals to explore the angular dependence of solid-solid friction were performed, and found to be consistent with theoretical predictions albeit complicated by noise in the measurements.
