Abstract

Effectiveness of Some Novel Heterocyclic Compounds as Corrosion Inhibitors for Carbon Steel

Author(s): Steve Michael

The importance of this work is to introduce new heterocyclic compounds as effective and low-cost corrosion inhibitors. Corrosion of carbon steel is a major problem that destroys the aids of industries and world steel installations; the importance of this work is to introduce new heterocyclic compounds as effective and low-cost corrosion inhibitors. 5-amino-N???-((2-methoxynaphthalen-1-yl)methylene) is one of three carbohydrazide derivatives. 2,4-diamino-N???-((2-methoxy-naphthalene-1-yl)methylene), isoxazole-4-carbohydrazide (H4) N???-((2-methoxynaphthalen-1-yl)methylene) and pyrimidine-5-carbohydrazide (H5 ) The corrosion efficacy of -7,7-dimethyl-2,5-dioxo-4a,5,6,7,8,8a-hexahydro-2H-chromene-3-carbohydrazide (H6 ) was investigated. Electrochemical Impedance Spectroscopy (EIS), Potentio Dynamic Polarisation (PDP), Weight Loss measurements (WL), surface morphology analyses by atomic force microscopy (AFM), quantum chemical computations based on density functional theory (DFT), and Molecular Dynamics (MD) simulation were used to detect this corrosion efficacy.
