Summary The nature of deposits on mild steel surfaces formed by exposure to corrosive and inhibiting solutions has been examined by attenuated total reflectance spectroscopy. For cerium-based inhibitors, e.g. CeCl3 the formation of cerium-containing coatings was detected whilst the cerium carboxylate Ce(sal)3 (sal=salicylate), which combines the Ce3+ with the known organic inhibitor sal, was shown to involve substantial deposition of both cerium and a salicylate species. These results, combined with corrosion inhibition data for the respective inhibitor compounds clearly indicate a synergistic corrosion mechanism for Ce(sal)3 which underpins the improved performance of this corrosion inhibitor in comparison to the individual components (i.e. Na(sal) or CeCl3).
