Abstract

Ultrasonic vibration is used to finely atomize liquid droplets in the electrostatic deposition of coatings on medical devices, such as intravascular stents. In such a system, quality atomization of a liquid coating is produced from the ultrasonic vibration and electrostatic repulsion. The only kinetic energy in the system is the attraction between the charged atomized particles and the grounded target.
