Resumen
In this work, the corrosion behavior of the 6061 Al-alloy in different temper conditions was studied in different soil extracts
using electrochemical and surface monitoring techniques. The results showed that the corrosion behavior of the 6061 alloy
depends on the soil extract composition, with the highest electrochemical activities related to the soil extracts with the lowest
nitrate and sulfate concentrations. The 6061-T6 condition was more susceptible to corrosion than the 6061-HCR one. The
results were related to the higher amounts of MgSi particles in the 6061-T6 alloy compared to the 6061-HCR. Sulfate and
nitrate ions acted as corrosion inhibitor reducing the corrosion kinetics of the 6061 alloy in solutions with high concentration
of chloride ions. Comiss??o Nacional de Energia Nuclear (CNEN) CNEN: SEI 01342.002357/2019-32
