Through control technological parameter of Nd:YAG pulse laser, current, pulse width, frequency, spot diameter, scanning velocity and defocusing, laser surface cladding Al-Y(1.4%) was used to repair corrosive damage of aluminum alloys. One group of the specimens was shocked on every cladding layer. After aging and fatigue test, crack pattern and microstructure were analyzed. The result showed that the fatigue life of the shocked specimens was much longer than the specimens’ without shock. The crack pattern of the shocked appeared fatigue strip, the microstructure showed there was no obvious pore and crack in the cladding layer which was metallurgy combination with the substrate.
