This study investigates the effect mechanism of water jet peening (WJP) on the surface integrity and fatigue performance of CoCrFeNiAl/Al6061 laminate composites. Through experiments and finite element simulations, the following results were obtained: At a jet velocity of 300mm/s, significant plastic deformation was observed in the core layer, and the maximum residual compressive stress increased from 679 MPa at 250 mm/s to 802 MPa, indicating that higher jet velocity promotes the development of residual stress. Core layer thickness plays a crucial role in fatigue life; specimens with a 1-mm-thick core layer exhibited lower fatigue life, while a 2-mm-thick core layer showed significant improvement. The jet velocity of 300 mm/s was the most effective in enhancing fatigue life.
