Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, ChinAbstract: The applications of laser peening in many fields, such as high-cycle fatigue, corrosion protection, biomedicaland precision forming, were summarized, and the advantages and pending problems of laser peening in the correspondingapplications were discussed, and the application development trends were analyzed. In the high-cycle fatigue andcorrosion protection field, the laser peening technology has been used in mass industrial production. In biomedical field,the laser peening technique has been developed toward industrial application. Laser peening for large panels forming hasgot small batch orders, and in the field of micro-electro-mechanical system, the application research of laser peening hasalso obtained good results which tends to practical application, so the application prospects are very optimisticMeanwhile, the diversified development direction of laser peening equipment was indicated for the specific needs ofdifferent applications and development stagesKey words: laser peening; high-cycle fatigue; corrosion protection; biomedical; precision forming随着航空、航天、武器、能源、交通领域高端装料的使役性能。然而传统的喷丸似、滚压等材料改备的发展,对其零件的使役性能要求越来越高,一方性技术因其引入的压应力层深度最大仅能达到面需研制具有高性能的材料,另一方面需加强现有材75-250um,以及成形困难,所以渐渐不再能满足高基金项目:国家高技术研究发展计划资助项目(2012A041310)收稿日期:2014-12-12;修订日期:2015-04-01通信作者:乔红超,翻研究员:电话:13840051605;E-mail;hcqiao)sia.cn
