The main aim of this study is to investigate Aganonerion polymorphum leaf-ethyl acetate extract (APL-EAE) and its inhibiting effect for steel in ethanol fuel blend. The immersion test, electrochemical and surface analysis techniques were successfully carried out in this research. Scanning electron microscope images indicated that the ethanol fuel blend induced pitting corrosion of steel. Remark...

We report the use of atomically thin layers of graphene as a protective coating that inhibits corrosion of underlying metals. Here, we employ electrochemical methods to study the corrosion inhibition of copper and nickel by either growing graphene on these metals, or by mechanically transferring multilayer graphene onto them. Cyclic voltammetry measurements reveal that the graphene coating effe...

Abstract: Despite having a number of advantages, reinforced concrete can suffer rebar corrosion in high–chloride media, resulting in failure of reinforced concrete structures. In this research the corrosion inhibition capability of the mixture of calcium and ammonium nitrate of steel rebar corrosion was investigated in the simulated concrete pore solution. Cyclic polarization and Electroche...

A novel Schiff base 2, 4- Bis (2‑hydroxy naphthaldehyde) diiminotholuene (L), was prepared and characterized by the analysis techniques: FT-IR, UV-Vis,1H 13C NMR. X-Ray Diffraction (XRD), showing that L crystallized in phenol-imine form. The corrosion inhibition of carbon steel 1 M hydrochloric acid solutions ligand studied using chemical (weight loss) electrochemical (potentiodynamic impedance...

Selection of an appropriate corrosion inhibitor, inhibitor combination or package is an exceptionally cost effective and materials saving measure in various industries. Current trends and novel approaches in corrosion inhibitors are reviewed here. Recent developments in the inhibition technology are discussed in accordance with the areas of application of inhibitors.

Švecová, University of Žilina, Faculty of Mechanical Engineering, Slovak Republic This work is focused on the effect of the laser surface treatment (laser power 50 and 80 W) on microstructure and corrosion properties of self-hardened AlZn10Si8Mg cast alloy used for engine and vehicle constructions. The electrochemical impedance sp...

A Fenton reaction and a corrosion inhibition strategy were designed for enhancing the polishing rate achieving corrosion-free Ge1Sb4Te5 film surface during chemical-mechanical planarization (CMP) of three-dimensional (3D) cross-point phase-change random-access memory (PCRAM) cells 3D synaptic arrays. The was conducted with 1,3-propylenediamine tetraacetic acid, ferric ammonium salt (PDTA–Fe) H2...

In Sweden, high level radioactive waste will be disposed of in a canister with a copper outer and a cast iron or carbon steel inner. If the iron insert comes into contact with anoxic geological water, anaerobic corrosion leading to the generation of hydrogen will occur. This paper presents a study of the anaerobic corrosion of carbon steel and cast iron in artificial Swedish granitic groundwate...

BACKGROUND The majority of well-known inhibitors are organic compounds containing multiple bonds and heteroatoms, such as O, N or S, which allow adsorption onto the metal surface. These compounds can adsorb onto the metal surface and block active surface sites, reducing the rate of corrosion. RESULTS A comparative theoretical study of three benzimidazole isomers, benzimidazole (BI), 2-methylb...

This study explored the effectiveness of tobacco extract as a corrosion inhibitor for carbon steel in an H2S-containing NaCl solution. The experiments were conducted at room temperature and atmospheric pressure, with variation concentration rate fluid flow. Results showed that decreases 3.5% Increasing flow significantly affect steel. In solution, crystalline product formation magnetite (Fe3O4)...
