Effect of Cu on the intergranular corrosion behavior of 6082 Aluminium Alloy
Abstract
The combination of unfavorable thermomechanical processing and the presence of copper may lead to the intergranular corrosion in 6000 series alloy. The intergranular corrosion susceptibility is strongly associated with Cu segregation during artificial aging and preferential precipitation of second-phase particles at the grain boundaries resulting in the growth of solute depleted zone adjacent to the grain boundaries. Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS), and Transmission Electron Microscopy (TEM) are employed to investigate the microstructure and the role of intermetallic particles in both heat-treated and as-received samples. The Microstructure and intergranular corrosion susceptibility of 6082 recycled aluminium alloy with different Cu content are investigated in this paper. The intergranular corrosion susceptibility is investigated in an aqueous solution containing 10 ml/L concentrated hydrochloric acid and 30g/L NaCl for 24 h. It is noticed that different Cu content gives rise to a considerable difference in the intergranular corrosion susceptibility. The results showed that the higher the Cu content the more the susceptibility of aluminium alloy to the intergranular corrosion. Moreover, it is found that the microstructure of the as-received samples consists of a double structure; a relatively thick recrystallized layer close to the surface, and a fully fibrous structure near the center of the samples. However, heat-treated samples showed a significant change in the microstructure as large elongated grains are observed near the core.
