Application of Ultrasonic Vibrations in the Course of Gluing

The results of studies on the application of ultrasonic vibrations to parts under gluing are presented. Resulting from cavitation treatment of the glue, its properties are improved, its viscosity decreases and the penetrating ability exhibits an increase. Under the conditions of ultrasonic vibrations, owing to an increase in the surface wettability and the sound-assisted capillary effect, the actual area of gluing increases. Depending on the treatment mode and the surface microgeometry, the application of vibrations leads to an increase in the strength of the adhesive joint from 8 to 43%.
