摘　　要：综述了喷丸强化技术对材料表层残余应力分布、显微组织结构、表面粗糙度和表层硬度分布等表面完整性因素影响的研究进展,阐述了不同喷丸强化技术与材料表面完整性因素间的关系以及基于表面完整性调控的喷丸强化技术的发展趋势。Shot peening is a kind of efficient, economical and effective surface peening technology and can improve mechanical performance of material remarkably through controlling surface integrity of peened material. The influence of shot peening on surface integrity are summarized, such as residual stress, microstructure, roughness and hardness and the relationship is introduced between different kinds of shot peening technologies and surface integrity in this paper. The fu- ture development prospects of shot peening research based on surface integrity control are summed up.
