THE INFLUENCE OF SURFACES NANOTOPOGRAPHY ON CHARACTERISTICS OF SOLIDS DISCRETE CONTACT

Abstract

The influence of nanoscale deviations of real surfaces of engineering devices from the perfect shape (nanoroughness) on real contact area has been considered. The real contact area ensures the electrical charges or heat transport through the contact of solids. It is shown that the neglecting of the nanoroughness in significant overestimation of real contact area.
