METHODS FOR WORK FUNCTION MEASUREMENTS FOR THE TEST OF A SURFACE IN A DURING FRICTION
Abstract
The paper describes the electronic work function measurements by the contact potential difference technique, and experimental demonstration of the possibility of their application for the monitoring of the friction surface. The techniques of tribological studies using contact potential difference probes are developed. Examples of measurements work function during friction for the bronze and steel samples are present. The study work function directly in the process of friction possible to determine the modes of friction and dynamics of defects on the surface friction, identify spots of destruction on local microroughnesses.
