Ultrasonic Technologies in Producing Adhesive Joints: A Review

Abstract: An overview of the current state of research on intensifying the processes of obtaining adhesive joints using ultrasonic vibrations is presented. Two types of ultrasound applications are considered: processing or preparing an adhesive composition before gluing and applying vibrations to the elements being glued. The main mechanisms that determine the increase in the properties of the resulting compounds are cavitation, which leads to the destruction of polymer chains and a decrease in the viscosity of the adhesive, and the sonic capillary effect, which consists in increasing the ability of the adhesive to fill micro- and submicron irregularities of the bonded surfaces. © 2023, Pleiades Publishing, Ltd.
