Sažetak
The use of corrosion inhibitors is one way of protecting Al against corrosion in acidic media.1, 2 Two non-toxic organic compounds, namely, eugenol and linalool were investigated as corrosion inhibitors for aluminium in 0.5 M HCl solution by weight loss, potentiodynamic polarization and EIS methods. Gravimetric measurements showed that the corrosion rate of aluminum in 0.5 M HCl was significantly reduced in the presence of compounds investigated. Potentiodynamic polarization curves indicated that presence of eugenol and linalool in HCl solution causes a prominent decrease in current densities. EIS measurements confirmed the existence of protective inhibitor film on the Al surface. The optimum concentration of eugenol was 0.012 mol L-1, while for linalool a concentration of 0.035 mol L-1 was necessary to attain its maximum inhibition efficinecy.
