Corrosion inhibition mechanism of six 2-amino-5-alkyl-1,3,4-thiadiazole compounds, for metal surface corrosion was studied by combining quantum chemistry, molecular mechanics and molecular dynamics simulation methods. Molecular reactivity parameters such as [Formula: see text], [Formula: see text], Fukui index were obtained and revealed that the change in alkyl chain length has little influence on the reactivity of thiadiazole inhibitor molecules. Molecular mechanics calculation results show that the molecule with elongated alkyl chain could form self-assembled membrane with higher stability and coverage rate to prevent the diffusion of corrosive substances to metal surface. Molecular dynamics simulation revealed the -equilibrium adsorption behavior of these thiadiazole molecules on metal surface and the calculated results were in agreement with the experimentally determined inhibition efficiencies.

Linear Polarisation

The corrosion inhibition of sodium deodecylbenzenesulfonate (SDBS) surfactant and ZnSO4 on mild steel in 0.05 M NaCl solution was conducted through the impedance spectroscopy and linear polarisation measurement. The inhibitors performance was measured separately and as a mixed composite of both at a ratio of 200:200 ppm. Results obtained from both these measurements indicate high corrosion inhibition of the mild steel substrates was achieved. Porosity calculation of the formed inhibition layer was done through the obtained linear polarisation data, and its dielectric properties were deduced from the impedance measurements. Two possible structures of the formed inhibitive layers are proposed. The first structure involved the formation of a stable but porous zinc oxide/hydroxide layer with the surfactant filling up the pores, thus forming a continuous inhibitive barrier film layer while the second, involved a formation of a continuous inhibitive barrier layer due to the chelation of the surfactant and ZnSO4 compounds. The results obtained also indicated that corrosion resistance induced by the inhibitive barrier layers is much more dependent on its charge transfer resistance properties rather than its dielectric properties and that the corrosion inhibition provided is not directly related to the double-layer capacitance values of the barrier layer.

Corrosion mitigation is an important aspect of amine-based post-combustion carbon dioxide (CO2) capture operations due to the desire to use less expensive but corrosion-vulnerable materials such as low carbon steels in the construction of a capture system. In this study, the corrosion behavior of A106 (grade B) carbon steel with an in-house proprietary amine-based solvent was investigated in a laboratory environment at 80 °C using an organic corrosion inhibitor, 2 Mercaptobenzothiazole (MBT). The corrosion inhibition mechanism was interpreted by electrochemical methods and surface analyses. The results revealed that the corrosion rates of carbon steel were significantly retarded using MBT. The critical inhibitor concentration was determined to be lie between 10 to 50 ppm under the tested conditions.
