Ultrasonic processing of metal works and powders

Abstract

Performance of elastic elements of automobile manufacturing and agricultural machinery is dependent on the state of the surface layer. Thus, strength, wear resistance, corrosion resistance, durability and reliability are determined by the state of surface layer of a product, which usually starts the destruction of material. Strengthening processing by superficial plastic deformation superimposed ultrasonic vibrations of high power allows the surface layers of products to create compressive residual stresses and micro- and nanostructured state. A method of ultrasonic treatment of the elastic plate and the inner surfaces of solids of revolution, developed by the authors, as well as ways and means for dispersing powders using powerful ultrasound are proposed.
