Tribological adhesion of particles in an acoustic field

Abstract

This paper investigates interaction between two particles in an acoustic field. It is shown that additional oscillating movements of particles occur as result of plain acoustic wave action. This sufficiently increases the probability of collisions between particles. Microdisplacements in the collision zone help to remove various pollutants, oxidation products and adsorbed gas molecules from surfaces of particles. Strong adhesive bonds are formed in the contact area between particles.
