摘要
Provided is a laser shock peening method for obtaining a large-area uniform surface morphology. Using the relationship between the thickness of an absorption layer and a plastic deformation due to the laser shock peening and using a grid-shaped absorption layer (5) having a staggered distribution in thickness in cooperation with a two-layer interlaced laser shock processing method significantly reduce the height difference between micro-protrusions (10) and micro-pits (12) produced by an impact of a square light spot, and effectively reduce the roughness of the workpiece surface such that a large-area uniform surface morphology is formed on the workpiece surface.
