Examination of corrosion and corrosion protection of the Al-2.5Mg alloy by the rotating disc electrode
The polarisation techniques and impedance spectroscopy measurements were used to determine the corrosion behaviour of the Al-2.5Mg alloy and inhibition efficiency of sinapinic acid as corrosion inhibitor in a deaerated 0.5 mol dm-3 NaCl solution. Sinapinic acid is a phenolic acid whose presence has been established in the plant material. Measurements were performed using a rotating disc electrode at different rotation rates (0 min-1, 150 min-1 and 2000 min-1) and at different temperatures (20°C, 30°C and 40°C). It may be concluded from the results obtained that the increase of the electrode rotation rate and temperature provokes a stronger corrosion attack on the alloy investigated. The addition of sinapinic acid inhibits corrosion of the Al-2.5Mg alloy but the inhibition efficiency decreases with the increase of the electrode rotation rate and temperature.
