Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a surface strengthening device and method for temperature-controlled assisted ultrasonic rolling. Background technique [0002] Ultrasonic surface rolling (USR) is a new type of surface modification processing technology. As one of the surface strengthening technologies, ultrasonic surface rolling can effectively reduce the surface roughness of the material and improve the surface microhardness of the material. Residual compressive stress can be generated, and at the same time, the microstructure of the surface layer of the material can be changed, so that the mechanical properties of the material can be effectively improved, and the corrosion performance, friction and wear performance and fatigue performance of the parts can be improved. [0003] USR processing is usually carried out at room temperature. However, a large number of studies and industrial practices have s...
