| The failure of engineering parts was often caused by the surface, and the working performance of engineering parts was significantly affected or even determined by the microstructural structure. The microstructural structure of materials was induced by the surface nanocrystalline surface layer, and the residual compressive stress on the surface layer increased, and the material performance was greatly affected. According to their characteristics, surface nanocrystalline technologies could be divided into three categories:surface self-nanocrystalline (mechanical and thermodynamic methods), surface coating/deposition and hybrid nanocrystalline. Firstly, the process and mechanism of microstructural changes induced by surface nanocrystallization were reviewed. The materials were induced to produce microscopic changes such as grain refinement, dislocation movement, increase of residual compressive stress and phase transformation, which were induced by plastic deformation, temperature change and element infiltration. Secondly, the influence and mechanism of surface nanocrystallization on material properties were summarized, and the fatigue strength, corrosion resistance, friction and wear properties and biological properties of materials were significantly affected by the above microscopic changes. The application, advantages and limitations of cold rolling, laser shock peening, shot peening, high pressure torsion, supersonic fine particles bombarding, surface coating/deposition and equal channel angular extrusion were summarized. Compared to other surface nano technology, ultrasonic vibration assisted treatment had no need to introduce other elements, no pollution, simple principle, high speed and high quality, low cost, could be on various advantages of the traditional processing technology, it had a positive effect on the friction and wear properties, fatigue properties, biological properties, surface wettability and corrosion resistance of materials. Finally, the future development of surface nanocrystalline technology was prospected, and the ultrasonic vibration assisted processing was analyzed. Digital simulation of the surface layer of nanocrystalline structure was extremely scarce. It needed more comprehensive and systematic research to combine simulation and experiment, analyze the mapping relationship between microstructure and processing parameters, microstructure and material properties, and establish a model for direct reflection. Some properties of the materials might be difficult to reach the optimal value at the same time, an evaluation system based on the above model needed to be established in order to improve the comprehensive properties of materials. The mechanism of nanocrystalline surface layer improving material properties was limited by existing observation methods and processing technology, the mechanism of surface nanocrystalline surface layer induced by surface nanocrystalline surface layer and high temperature stability based on phase transformation dynamics still need to be further analyzed and explored. The key of ultrasonic vibration assisted machining technology included ultrasonic vibration unit, ultrasonic cutting tool, ultrasonic cutting machine tool, ultrasonic system, CNC machine tool integration technology, etc. These key restricting factors needed to be improved, the development of new materials and the improvement of technical means were important research contents. Surface nanocrystalline methods generally affected only relatively shallow layers of materials, the improvement of the overall properties of the material was restricted. The combination of ultrasonic vibration-assisted machining with other surface nanocrystallization methods was an area that could be explored, and complementary advantages might further induce better material properties. |
