摘　　要：超声波喷丸强化技术近年来已经在多种类零件的制造工艺中引起高度关注。超声波喷丸强化技术能够对被处理材料实现表面改性,强化其物理、化学特性,其设备结构紧凑,可并入生产线上,方便操作、重复性好、无污染、噪音小,便携式的超声波喷丸设备在表面强化技术领域有巨大优势。综述了超声喷丸表面强化技术目前国内外研究和应用现状,论述了超声波喷丸表面强化技术的强化机理和技术特点,重点介绍了强化件残余应力场研究以及表面纳米化研究,总结了超声波喷丸表面强化的关键技术和难点,超声波喷丸表面强化技术有着广阔的应用前景。Ultrasonic shot peening （USP） has recently had signicantly more attention in several manufacturing processes. USP modifies the surface of a material and enhances the mechanical and/or chemical properties, and has compact device structure,convenient operation, good repeatability, no pollution, little noise. Portable ultrasonic peening equipment has great advantages in the field of surface strengthening technology.The current review paper has been devoted to introduce this technology for its underlying mechanisms and effects.The research and application of ultrasonic shot peening technology is summarized. The strengthening mechanism, technical characteristics, research and analysis of the residual stress field and the key technology of surface nano analysis are emphatically introduced. Key technolopies and diffculties of ultrasonic shot peening surface hardening technology are summarized,and its prospect is wide.
