The laser-induced damage of aluminum alloy 5083 is affected by its surface treatment. Here, we investigate the effects of aluminum alloy's ability of laser-induced damage on micro-arc oxidation and composite coatings treatment. Results demonstrate a distinct difference of damage parameters on laser pulse duration at 355 nm between micro-arc oxidation and composite coatings treatment on aluminum alloy, including the laser-induced damage threshold, particulate pollutants for different surface treatment, and the damage morphology, respectively. We now find that the threshold of laser-induced damage is improved a lot through simulative calculation and experiments. Furthermore, the experimental results suggests that surface treatment contribute to the number of particulate pollutants and the microstructure of damaged pit.
