Inhibition of corrosion of SS 18/8 alloy is sea water by Thiourea-Zn2+ system
نویسندگان
چکیده
The corrosion resistance of SS 18/8 in natural sea water, presence an inhibitor named Thiourea-Zn2+ has been evaluated. Weight loss method, polarization study and AC impedance spectra have employed to evaluate the alloy system. method reveals that system offers a maximum inhibition efficiency 95% controlling water. Synergism parameters are found be greater than 1, confirming synergistic effect existing between Thiourea-Zn2+. Adsorption molecules on metal surface obey Langmuir adsorption isotherm. Polarisation inhibitors functions as mixed type inhibitor. confirm formation protective film surface. This formulation may used cooling water systems where pipelines carry which is coolant. Also, coating can given protect it from by when hull plates ship industry.

The inhibition efficiency (IE) of Thiourea (TU) in controlling corrosion of carbon steel in sea water in the absence and presence of Zn 2+ has been evaluated by weight loss method. The formulation consisting of 200 ppm TU and 50 ppm Zn 2+ has 95% IE. A synergistic effect exists between TU and Zn 2+ . Synergism has been confirmed by Synergism parameter and F-Test. Influence of immersion period a...

In this paper, quantum chemical parameters at density functional theory (DFT) B3LYP/6-31G** (d,p) level of theory were calculated for three organic corrosion inhibitors [N-benzoyl-N-(p-aminophenyl) thiourea, N-benzoyl-N-(thiazole) thiourea and N-acetyl-N-(dibenzyl) thiourea. The calculated molecular descriptors such as the HOMO, LUMO, dipole moment, chemical potential (μ), chemical hardness (ղ)...
متن کاملCorrosion of Concrete in Sea Water (RESEARCH NOTE)
Attack and disintegration of concrete structures under the influence of aggressive fluids, wet gases, etc. are understood as corrosion of concrete. The corrosion of concrete is a chemical, colloidchemical process, yet often a physico-chemical one, while that of reinforced concrete supported oil platforms are subjected to marine environment in the Persian Gulf and therefore corroded. In the pres...
