摘　　要：工程材料疲劳延寿与复杂构件表面改性等应用需求不断提高,对激光冲击表面改性工艺进行合理改进和优化已尤为迫切。本文针对激光冲击处理在航空制造等重大工业领域所面临的具体需求,综述了新近发展的若干工艺改进方法。所涉及工艺策略摆脱了激光冲击对高性能激光器的设备依赖,从非激光参数调整的角度实现更具经济性和可行性的表面防护与加工。所指非激光参数包括吸收层、约束层以及激光与材料离焦状态等可调节指标,该类指标的工艺设定区间广泛且易控,体现出良好的异形构件适应性。所涉及新方法、新技术有望推动研究人员进一步探索绿色激光的应用潜力。With the further improvement of material fatigue life extension and processing of parts with complex shapes,laser shock processing has encountered more and more obstacles in practical applications and it is particularly urgent to improve and optimize the specific processing methods in laser shock treatments.Using the stress effect produced by pulsed lasers to process materials in various fields still has broad prospects.Given the specific needs of laser shock in different industrial applications,several processing improvement methods which get rid of the equipment dependence on high-performance laser units were proposed.The non-laser parameters include adjustable indicators,such as absorption layer,constraint layer,and defocusing state between laser and material.The selected material,thickness,and other related attributes of the absorption layer and the constraint layer directly affect the intensity of laser-induced shock waves,while changes in defocusing amount lead to differences in physical or chemical effects on the material surface.The process setting range for the above non-laser indicators is wide,easy to control,and can reflect good adaptability of irregular components.The development of new technologies for equal/unequal-strength and high-strength surface strengthening based on changes in these indicators,as well as new green packaging technologies such as laser marking,were introduced in detail.The new ideas behind these new methods are expected to inspire researchers to further explore the application potential of green lasers.
