摘　　要：航空发动机部件服役环境恶劣、工作载荷复杂,容易发生高周疲劳断裂,严重影响发动机安全可靠性。激光冲击强化是一种新兴的表面塑性强化技术,可通过残余压应力预制和微观组织改善显著提升金属材料高周疲劳性能,已在航空发动机部件生产和修理中实现了批量化应用。将深入讨论风扇/压气机叶片、涡轮叶片、涡轮盘、机匣、作动筒、导管、齿轮等部件激光冲击强化研究进展和应用情况及有待解决的问题,分析总结近年来航空发动机部件激光冲击强化研究历程及特点,并就未来设备、机理、工艺和应用等方面研究进行展望,希望通过全行业、全技术链的力量创新协同,推动激光冲击强化技术在我国航空发动机部件上的规模化工业应用。Because of hostile service environment and complicated working loads, aero-engine components are apt to high-cycle fatigue fracture, which seriously affects security and reliability of aero-engine. Laser shock peening, LSP, is a novel surface plastic-strengthening technology. High-cycle fatigue performance can be improved effectively under the action of compressive residual stress and microstructural modification. LSP has been widely applied in the batch production and maintenance of aero-engine components. Research status, application situation and problems to be resolved of laser shock peening on fan/compressor blade, turbine blade, turbine disk, cartridge receiver, hydraulic actuator, pipe, gear and so on were discussed deeply. The development tendency of laser shock peening research on aero-engine components in recent years was analyzed and concluded. The future work on equipment, technique, mechanism and application of laser shock peening on aero-engine components was taken an outlook. In future, hope that the large-scale industrial application of laser shock peening on aero-engine components could be realized under the synergistic action of the whole industry and the whole technology chain.
