With the rapid advancement of modern aviation technology

critical load-bearing components are subjected to complex service environments involving cyclic loading

high-temperature oxidation

and severe vibrations. These harsh conditions often lead to fatigue cracking

stress corrosion cracking

and high-temperature creep failures

posing serious threats to the safety and reliability of aerospace equipment. Laser shock peening can introduce deep residual compressive stresses into the surface layer of materials

significantly enhancing fatigue performance and corrosion resistance

and has been successfully applied to components such as engine blades and landing gears. However

conventional single-process laser shock peening technology faces limitations in terms of plastic deformation depth

microstructural control

and uniform strengthening of complex geometries. In recent years

energy field assisted laser shock peening has emerged by incorporating auxiliary energy fields such as ultrasonic vibration

electric pulses

magnetic fields

thermal fields

and cryogenic environments. This approach enables deeper energy coupling and precise multiscale microstructural regulation

significantly improving fatigue life

corrosion resistance

and high-temperature service performance of materials. This paper reviews the mechanisms and current applications of energy field assisted laser shock peening in aerospace components

focusing on the effects of different auxiliary fields on microstructural evolution

residual stress distribution

and mechanical property enhancement. Case studies on aerospace blades

turbine disks

and landing gears are presented to highlight its advantages in improving fatigue resistance

corrosion resistance

and structural reliability. Finally

future trends and potential applications of energy field assisted laser shock peening in intelligent manufacturing and surface strengthening of high-performance aerospace materials are discussed

providing theoretical guidance and engineering references for optimizing the comprehensive performance of critical aerospace components.
