The inhibition efficiency depended on MBO concentration, existence of NaCl and the immersion period of the copper sample. The inhibition efficiency of about 99% could be obtained by immersing for above 20 h in 3% NaCl + 1 mM MBO solution. The surface of the copper sample immersed in NaCl + MBO solution possessed FTIR characteristics different from those of MBO solution, irrespective of immersion time. The in-situ STM morphologies showed the rapid formation of a three-dimensional compact inhibition film on the surface of copper in MBO solution containing NaCl. XPS indicated that the inhibition film was cuprous and the chemical environments of S and N atoms were evidently changed. It is concluded that MBO reacted with the cuprous species from the corrosion process, and produced a water-insoluble cuprous complex to form the inhibition film and to retard the corrosion of copper.

The corrosion behavior of bronze in the presence of AMT has been investigated in 5% citric acid. Electrochemical potentiostatic polarization method and electrochemical impedance spectroscopy (EIS) were applied to analysis the effect of the organic compound on the corrosion inhibition of bronze. The results showed that AMT could greatly retard the corrosion of bronze in citric acid, which was attributed mainly to the protective film formed by AMT. Fourier transform infrared (FTIR) was used to characterize the surface film. A polymeric Cu (I) -inhibitor complex exhibiting strong corrosion inhibition that totally covered the bronze surface was identified. AMT behaves as bidentate ligand through the aminic nitrogen atom and the closed ring nitrogen in these complexes.","authors":[],"categoryName":"|","doi":"","fpage":"604","id":"36aecd04-a292-4cdf-9641-5f601bde0835","issue":"7","journal":{"abbrevTitle":"APS","id":"917def08-6dcf-48e9-9603-bf5509ffd610","issnPpub":"1000-6818","publisherId":"APS","title":"Acta Physico-Chimica Sinica"},"keywords":[{"id":"48dfa425-1025-4056-aa11-b4f43df65ce0","keyword":"2-amino-5-mercapto-1,3,4-thiadiazole (AMT);bronze;citric acid;inhibitor;FTIR;2-amino-5-mercapto-1,3,4-thiadiazole;benzotriazole","originalKeyword":"2-amino-5-mercapto-1,3,4-thiadiazole (AMT);bronze;citric acid;inhibitor;FTIR;2-amino-5-mercapto-1,3,4-thiadiazole;benzotriazole"}],"language":"en","publisherId":"1000-6818_2001_7_1","title":"The inhibition of AMT on bronze corrosion in 5% citric acid","volume":"17","year":"2001"},{"abstractinfo":"The corrosion inhibition for carbon steel in circulating cooling water by modified lignosulphonate has been investigated using electrochemical impedance spectroscopy technique.

Met functioned as a better inhibitor for both Fe microstructures, and was more favorably adsorbed on the nanocrystalline surface. The nanocrystalline surface however diminished adsorption of Phe. The comparable values of our computed physisorption energies (-94.2 kcal mol(-1) and -86.6 kcal mol(-1) for Phe and Met respectively) as well as the stable adsorption orientations of both molecules on Fe suggest a controlling influence of a soft epitaxial adsorption mechanism in which C, N, O, S atoms of the molecules align with epitaxial grooves on the Fe lattice. The significant contribution of physisorptive interactions also correlates with the similarity in experimental inhibition efficiencies on polycrystalline Fe (Phe = 73% and Met = 82%), though for Met the thiol group imparts an added ability for covalent interaction with Fe, which accounts for the higher efficiency. Furthermore, we have related the diminished inhibition efficiency of Phe on the nanocrystalline Fe surface to disruption of the epitaxial patterns on the lattice as the surface becomes increasingly defective, leading to weaker adsorption. The improved efficiency of Met on the nanocrystalline surface is related to scaling up of the covalent interactions around defect sites. Our theoretical conclusions are validated by the consistency with our experimental findings.","authors":[],"categoryName":"|","doi":"","fpage":"866","id":"9f502859-cda6-41bf-bbce-d039f265fc44","issue":"5","journal":{"abbrevTitle":"RA","id":"d7a641af-4cde-427c-adca-49aefe1b9e83","issnPpub":"2046-2069","publisherId":"RA","title":"Rsc Advances"},"keywords":[{"id":"1a42fc7d-3bf0-4a51-9fac-f3355fc34cb4","keyword":"universal force-field;mild-steel corrosion;molecular-structure;organic-compounds;sulfuric-acid;carbon-steel;simulation;copper;iron;dft","originalKeyword":"universal force-field;mild-steel corrosion;molecular-structure;organic-compounds;sulfuric-acid;carbon-steel;simulation;copper;iron;dft"}],"language":"en","publisherId":"2046-2069_2011_5_1","title":"Understanding corrosion inhibition mechanisms-experimental and theoretical approach","volume":"1","year":"2011"}],"totalpage":18,"totalrecord":173}
