A Critical Review of Laser Shock Peening of Aircraft Engine Components

Many aviation accidents are caused by the failure of aircraft engine components, and blades especially vulnerable to high‐cycle fatigue fracture in severe working environments as well impact damage foreign objects. To address this problem, United States took lead has been successful implementing laser shock peening (LSP) a surface treatment for components enhance their performance. This review provides an overview development LSP use treating over past three decades, with brief introduction high‐energy pulsed lasers LSP. A particular focus is on limitations challenges associated application critical components. It hoped that serves reference future research can better performance these
