Schematic diagram of Hulk energy ultrasonic surface strengthening treatment
Its principle is to use the composite energy of activation energy and impact energy to process metal parts, so as to obtain a new processing technology of mirror parts and surface modification. It uses the principle of cold plasticity of metal, and under the action of activation energy, the metal surface undergoes plastic rheology, and the high-frequency impact of 30,000 times per second causes the surface tissue of the workpiece to flow and deform, cutting peaks and filling valleys, and reaching the mirror surface. At the same time, the grain is refined to nanometer level, and the compressive stress is preset, so that the surface modification of metal workpiece can reach high strength, high hardness, high toughness and ductility, and excellent wear resistance and corrosion resistance can be produced.
