The paper presents an overview of studies of the corrosion destruction mechanisms of aluminum alloys in seawater. The main factors that have the greatest impact on corrosion are considered: physical and chemical parameters, the depth of the test objects, as well as the role of biofouling. It has been determined that the parameter of the species composition of the fouling organisms is an important factor in the corrosion of metals in seawater and should be taken into account when identifying the mechanism of corrosion destruction during tests under various conditions.
