Abstract
This study assesses the ability of Griseofulvin and Amoxicillin, two expired medicinal medications, to suppress corrosion on AA6063 aluminium alloy in a 1 M HCl environment. Aluminium alloys, such as AA6063, are prone to corrosion, especially when exposed to acidic environments and chloride ions. The electrochemical behaviour of AA6063 was evaluated at different temperatures (30 °C, 40 °C, 50 °C, and 60 °C) and concentrations (0.2 g, 0.4 g, and 0.6 g for Amoxicillin; 0.2 ml, 0.4 ml, and 0.6 ml for Griseofulvin) using potentiodynamic polarisation. The inhibitory mechanism was investigated using adsorption isotherms. The results show that both drugs successfully slow down the rate of corrosion, with griseofulvin working better at lower dosages. At higher temperatures, however, the efficacy of inhibition reduced, indicating a physisorption mechanism.
