The aim of this paper is to investigate tomato pomace extract (TPE) as multifunctional "green" vapor phase corrosion inhibitor for prevention of the atmospheric corrosion of mild steel and as corrosion inhibitor in neutral media of 0.5 M NaCl solution. The chemical profile of the TPE was analysed using gas chromatography mass spectrometry (GC-MS) and high performance liquid chromatography analysis (HPLC-DAD-MS). The major volatile constituents identified in tomato pomace extract were alcohols (12.5 %), fatty acids (23.78 %), aldehydes (41.6 %), ketones (8.65 %), and terpenoids (9.11 %). The predominant semi-volatile and high molecular weight chemical components in tomato pomace extract were phenolic acids and flavanols. The corrosion protection properties of the TPE as multifunctional corrosion inhibitor were studied using of accelerated corrosion tests (weight loss method) and electrochemical methods (polarization curves and linear polarization technique (LPR)). The mechanism of steel inhibition by TPE formulations was studied by scanning electron microscopy (SEM) and atomic force microscopy (AFM) observations. The analysis confirmed that the growth of inhibitory properties is prolonged and corrosion rate is reduced after 40 -48 h of exposure.Quantum-chemical calculations were used to predict the adsorption/inhibition properties of some of the main compounds of the extract.

“…The N 1s peak at 397.99 eV corresponds to the N atom in ALA, and the 399.69 eV peak corresponds to the N atom coordinated to the Fe atom on the metal surface. In Figure 7(b), the O 1s peak has a binding energy of 528–534 eV, corresponding to the O atom of ferrous oxide (FeO) and the O atom interacting with the iron atom in ALA molecule, respectively (Zhang et al , 2020). In Figure 7(c), the Fe 2p3/2 peak at 710.15 eV and 713.56 eV is corresponding to the oxidation state, and at 706.60 eV to the binding of iron atoms to ALA molecules.…”

Purpose The aim of this paper is to solve the toxic and harmful problems caused by traditional volatile corrosion inhibitor (VCI) and to analyze the effect of the layered structure on the enhancement of the volatile corrosion inhibition prevention performance of amino acids. Design/methodology/approach The carbon dots-montmorillonite (DMT) hybrid material is prepared via hydrothermal process. The effect of the DMT-modified alanine as VCI for mild steel is investigated by volatile inhibition sieve test, volatile corrosion inhibition ability test, electrochemical measurement and surface analysis technology. It demonstrates that the DMT hybrid materials can improve the ability of alanine to protect mild steel against atmospheric corrosion effectively. The presence of carbon dots enlarges the interlamellar spacing of montmorillonite and allows better dispersion of alanine. The DMT-modified alanine has higher volatilization ability and an excellent corrosion inhibition of 85.3% for mild steel. Findings The DMT hybrid material provides a good template for the distribution of VCI, which can effectively improve the vapor-phase antirust property of VCI. Research limitations/implications The increased volatilization rate also means increased VCI consumption and higher costs. Practical implications Provides a new way of thinking to replace the traditional toxic and harmful VCI. Originality/value For the first time, amino acids are combined with nano laminar structures, which are used to solve the problem of difficult volatilization of amino acids.

The protective effect of chamber steel corrosion inhibitors based on lauric acid has been studied by electrochemical and corrosion methods. It has been established that its protective effect can be enhanced by additives of octadecylamine, as well as octadecylamine and benzotriazole or its derivatives-tolyltriazole and chlorobenzotriazole. The mechanism of action of all studied compositions and their components is blocking-activating, with a predominance of activation. The protective effect of the studied mixture inhibitors considerably exceeds the protective effect of the components. Nevertheless, an analysis of the mutual influence of the components indicates the absence of their synergistic interactions. It was shown by ellipsometric methods that adsorption of the studied inhibitors inhibits or prevents oxide growth on steel during chamber treatment. During chamber treatment of steel with the studied inhibitors nanosized adsorption films are formed on its surface. There is no unambiguous correlation between their thickness and the protective effect of chamber inhibitors, but the most effective compositions are characterized by the thickness of the adsorption layers of 10 nanometers or more.
