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.
