The 18th International Corrosion Congress took place between the 20th and the 24th November 2011 in the Perth Convention and Exhibition Centre, Australia. The International Corrosion Congress is the major event of the International Corrosion Council (ICC), an international body founded to advance corrosion science and engineering and is held once every three years by different host countries. This edition has undoubtedly been one of the major successes of the ICC, with many participants, a high level contribution from all over the globe, and a lively social atmosphere in between sessions and the evenings.
