Marine engineers and naval architects recognize Al alloy as an advantageous material in shipbuilding and the fabrication of components in offshore platforms. The lightweight, superior mechanical properties of Al alloy have dictated their use in many of these applications. In particular, the 5083 series Al alloy is widely used as a material for ship structures because it not only has all the unique advantages of aluminum, but also has excellent machinability and weldability. However, the Al vessels were occurred cavitation erosion and corrosion due to the rapid speed and Cl- ions in seawater at the same time. Therefore, in this study, it evaluated the corrosion behavior of 5083-O Al alloy with amplitude in cavitation environment. As results, the damage with increasing amplitude was larger by increasing the impact energy of cavity that delivered to the surface.
