ABSTRACT
The ultrasound-assisted lowering of working forces can be estimated theoretically through changes in the workpiece material properties and processes occurring at the workpiece-tool contact surface. This chapter considers ultrasound as a potential tool to be used in various thermal and thermochemical treatment processes. In combination with chemical treatment, it appears to be a highly efficient approach to material processing along with thermomechanical, mechanothermal, and thermomagnetic methods. Ultrasound is well suited to industrial applications associated with electrochemical coatings and improvement of their quality. Biront over viewed the studies dealing with the aging of alloys placed in fluids vibrated at sonic and ultrasonic frequencies. V. P. Severdenko and his colleagues Dr. V. V. Klubovich and Dr. A. V. Stepanenko who carried out a wide range of research into a potential use of ultrasound in metalworking. Among coating methods, the hot dip process, in which the base surface is brought into a contact with the plating metal melt, is of special importance.
