摘要：

Lanthanum and cerium chloride and their binary mixtures have been investigated as corrosion inhibitors of AA5083 Al-Mg alloy in aerated 3.5% NaCl aqueous solution. Their inhibitor power was evaluated by using electrochemical techniques together with full immersion tests. The highest protection degree was found for the binary solution doped with 250 ppm CeCl3 and 250 ppm LaCl3. Scanning electron microscopy and energy dispersive spectroscopy enabled us to confirm the cathodic nature of the inhibition process and to establish some features of the inhibition process. © 2001 Elsevier Science B.V.
