CHARACTERIZATION AND SUSCEPTIBILITY TO INTERGRANULAR CORROSION OF AA2024 ALUMINUM ALLOY

In this work, has been performed the characteristics and susceptibility to intergranular corrosion of high strength alloy of AA2024-T3 in alkaline media. Intergranular corrosion can occur randomly over the entire surface of an alloy, but corrosion is limited to the immediate area of the grain boundary and is often not apparent by simple visualization. It can be an important source of limiting the life of the aircraft body where alloys from the 2xxx series are used, which is why they are systematically subjected to intergranular corrosion tests in dedicated laboratories.
