| The ultrasonic surface rolling process (USRP) refines the grain to nanometer level through the annihilation and generation of dislocation, which improves the hardness and wear resistance of the material. The strengthening mechanism of USRP technology mainly includes dislocation strengthening and fine grain strengthening. By applying ultrasonic frequency mechanical vibration with a certain amplitude along the normal direction of the surface of the component with a rolling head, the static pressure and ultrasonic shock vibration of the rolling head are transmitted to the rotating or static surface of the mechanical component under a certain feeding condition, which results in periodic extrusion and obvious plastic deformation of the metal material surface. Besides, dislocation is easy to occur on the metal material surface under the action of USRP, and the dislocation density increases with dislocation initiation and entanglement. The continuous annihilation and generation of dislocation refine the surface to the nanometer level, and then form a gradient nanolayer. This can reduce the surface roughness of the material and improve the surface properties such as hardness, wear resistance and corrosion resistance, which is beneficial to the surface properties of the material. The work aims to explore how to further improve the serviceability of the material by combining USRP with other processing technologies to form a composite processing technology to overcome some of the limitations of a single USRP technology, such as the limit of plastic deformation or the defects of crushing caused by excessive strengthening. After USRP treatment, shear deformation and local fatigue damage will occur on the surface of the material, resulting in reduced deformation resistance. In addition, the severe plastic deformation will cause the hardness of the surface strengthening layer to increase, which can not be significantly improved in the subsequent process. The strengthening effect of USRP is also limited by the material itself. Therefore, the combination of USRP and other processing technologies to form a composite processing technology is an effective way to further improve the properties of materials. USRP composite strengthening technology, as a special composite processing technology, has obvious advantages in the high-performance manufacturing of parts. According to the position sequence of USRP in the composite process, three processing types are introduced, including USRP front-end strengthening, synchronous strengthening and follow-up strengthening respectively. USRP front-end composite machining technology includes USRP composite vapor deposition technology and USRP composite ion implantation technology. The effects of acoustic and electric coupling and temperature field assisted USRP on the thickness and friction and wear properties of the deformed layer are discussed. In the follow-up strengthening of USRP, the composite USRP technology of the coating is introduced, and its effects on crack healing, pore reduction and surface roughness reduction are discussed. USRP, as a front-end strengthening technology, can accelerate the ion diffusion rate. The electrical pulse and temperature promote the movement of the dislocation, and the energy input enhances the ability of the dislocation to cross the barrier, increases the number of dislocations, and thus improves the plastic deformation ability of the metal surface. USRP as a follow-up strengthening technology can enhance the adhesion between the coating and the substrate, eliminate the pores in the coating, repair cracks and reduce the surface roughness of the material. In addition, the mechanism of USRP on the microstructure evolution and plastic deformation of materials during the composite strengthening process is analyzed, and the current research status of these technologies in improving the surface strengthening effect and meeting the complex service requirements is summarized. Finally, the application prospect and development direction of USRP composite strengthening technology in the future are prospected, and its research value and goal in improving the serviceability of materials are emphasized. |
