Corrosion is a major challenge in various industries and can cause significant damage to metal structures. Organic corrosion inhibitors are compounds that used reduce or prevent by forming protective film on surfaces. The present review article focuses natural synthetic organic their classifications, active functional groups, efficiency estimations. Furthermore, previous studies the use of disc...

The anticorrosion potency of Sabic mild steel (MS) in 0.5 M H2SO4 solution was enhanced by three synthetic non-ionic surfactants (NI Surf.) containing pyridine and pyrimidine derivatives. These compounds are safe, environmentally friendly, harmless to human health. Chemical electrochemical measurements were used compute the corrosion parameters. efficacy increases with increasing concentration ...

The adsorption behavior of Benzimidazol-2-one (Bz), 5-Methylbenzimidazol-2-one(CH3Bz) and 5-Chlorobenzimidazol-2-one (ClBz) as inhibitors for mild steel corrosion in HCl 1M have been studied computationally using density functional theory (DFT) calculations with the hybrid B3LYP functional. The calculations were focused on the protonated forms of the molecules under study, seeing tha...

the Corrosion inhibition of mild steel in 1 M HCl has been investigated using three dendrimers by means of gravimetric, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, scanning electron microscopy (SEM) and energy dispersive Xray spectroscopy (EDX) techniques. Results showed that inhibition efficiency increases with increasing concentration of dendrimers. Among the s...

Plant extracts are extensively researched as a source of green corrosion inhibitors. Herein, we report on a highly efficient and thermally stable corrosion inhibitor from the stem extract of high-altitude shrub Berberis aristata. The corrosion inhibition efficiency (IE) of the extract was tested in 1.0 M H2SO4 for the corrosion protection of mild steel (MS) by using gravimetric and electrochemi...

With the current emergence of green chemistry to keep the environment safe, attention is being shifted towards using plant extracts as corrosion inhibitors. The inhibitive performances of Talinum triangulare leaf extract and Musa sapientum peel extract on the ZA-27 in 1.0 M and 1.5 M hydrochloric acid solutions were studied for 18 days using mass loss measurement. The corrosion inhibition effic...

The heterogeneous structure of Al alloys renders them susceptible to localized corrosion due to the different electrochemical properties existing in the Al-rich solid solution matrix and secondary phase particles. The galvanic interactions between these two phases can result in pit formation either through dissolution of the particles or corrosion of the matrix adjacent to the particles. This d...
