Research on Strengthening Aerial Aluminum Alloy with Laser Shock Peening

Zhuang Ma

Abstract

The mechanism of laser shock peening and application of the coating and limiting layer are studied. Thelaser shock peening experiment of LY2 aerial aluminum alloy is carried out and its capability is tested.The influence on the fatigue life and hardness of aerial aluminum alloy after laser shock peening are analyzed.
