Abstract
Description
technical field
[0001] The invention relates to the field of metal surface processing, in particular to an induction heating assisted surface ultrasonic rolling device and method. Background technique
[0002] Ultrasonic surface rolling process (USRP) is a new surface modification processing technology, which combines ultrasonic vibration with traditional surface deep rolling technology. Plastic deformation makes the surface of the material nano-scale, while increasing the hardness, it also introduces a higher residual compressive stress on the surface of the part, and can also greatly reduce the surface roughness, thereby improving the mechanical properties of the material, improving the corrosion performance of the part, friction and wear performance and fatigue performance.
[0003] However, with the development of science and technology, in some special working conditions (high temperature environment, corrosive medium and high stress, etc.), conventional surface ultras...
