Abstract: This paper examines the economic costs and benefits of the use of an ultrasonic wire or tape cleaning system. In the last years, major technology improvements made the use of power ultrasound more reasonable for the cleaning of wires. The cavitation of modern high-power ultrasonic processors serves to remove grease, oil, and other contaminations from the surface of the wire. Reduced investment costs and high performance of these ultrasonic wire cleaning systems made them not only competitive but superior to conventional cleaning methods as for example acid baths.

Abstract: Applications of power ultrasonics in engineering are growing and now encompass a wide variety of industrial processes and medical procedures. In the field of power ultrasonics, ultrasonic vibrations are used to effect a physical change in a medium. However, the mechanism by which a process can benefit from power ultrasonics is not common for all applications and can include one or more of such diverse mechanisms as acoustic cavitation, heating, microfracture, surface agitation and chemical reactions. This paper presents two applications of power ultrasonics involving some of these different characteristics by concentrating on two case studies involving material failure (ultrasonic cutting) and acoustic cavitation (bacterial inactivation).
