The Mechanism of the Tribo Effect

Abstract

Electrification in friction has been studied quantitatively. Glass balls were rolled through a glass tube and fall into a Faraday cage. The individual charges on 150-200 balls were recorded and evaluated statistically. Primary variables are rate f of feed of balls into the tube (f = 1 to f = 70 balls per minute) and time T spent by each ball in the tube. An empirical formulae was obtained for the average absolute charge q and the fraction of positive balls. The mechanism of charge generation has been identified as to its main features. Friction causes disturbance of the equilibrium between the glass surface and the atmosphere and reactions occur to restore this equilibrium. These reactions are oxidation - reduction reactions.
