Resumo |
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. CeCl<sub>3</sub> the formation of cerium-containing coatings was detected whilst the cerium carboxylate Ce(sal)<sub>3</sub> (sal=salicylate), which combines the Ce<sup>3+</sup> with the known organic inhibitor sal<sup>−</sup>, 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)<sub>3</sub> which underpins the improved performance of this corrosion inhibitor in comparison to the individual components (i.e. Na(sal) or CeCl<sub>3</sub>).<br /> |
