摘要
综述了高能喷丸、超声表面强化、超音速微粒轰击和激光冲击改性等表面纳米化技术的研究现状。表面纳米化在提高硬度、耐磨性、耐蚀性、疲劳性和扩散性能等方面具有积极作用。最后提出钢材表面纳米化技术发展中需注意的问题。
The research status of surface self-nanocrystallization was reviewed, which included high energy shot peening（HESP）,ultrasonic surface strengthening,supersonic fine particles bombarding（SFPB） and laser shock peening（LSP）. The surface self-nanocrystallization has a positive role in improving the hardness,wear resistance corrosion resistance,fatigue properties and diffusivity. At last, the problems existing in the development of surface nanocrystallization technology of steel were proposed.
