Electrochemical and quantum chemical studies of some azomethine compounds as corrosion inhibitors for mild steel in 1M hydrochloric acid

Corrosion inhibition of mild steel by two new S-heterocyclic compounds in 1 M HCl: Experimental and computational study

“…The study of corrosion inhibition of mild steel using organic inhibitors mainly in acidic media is one of the most important subjects of current research in different industries [1][2][3]. Mild steel is widely used as structural material in engineering as well as daily life applications [4,5].…”

Experimental and theoretical studies of xanthan gum and its graft co-polymer as corrosion inhibitor for mild steel in 15% HCl

“…The corroded metal surface was characterized by scanning electron microscopy (SEM). Quantum chemical methods are very useful in determining the molecular structure as well as in elucidating the electronic structure and reactivity of inhibitors [17]. The energy of the highest occupied molecular orbital (E HOMO ), the energy of the lowest unoccupied molecular orbital (E LUMO ), the energy gap ( E) were calculated by Density Functional Theory (DFT).…”

Investigation of polyacrylamide containing capsaicin monomer as a novel corrosion inhibitor for mild steel in hydrochloric acid

“…This work studies the inhibition efficiency of PAMAHS for carbon steel in hydrochloric acid solution at 298 K. The inhibition efficiencies of polyacrylamide and PAMAHS were compared using a gravimetric experiment in 1 M hydrochloric acid solution. Electrochemical polarization measurements and electrochemical impedance spectroscopy were also used to evaluate the inhibition properties . Surface characterization techniques such as laser scanning confocal microscopy, SEM and contact angle analysis were carried out to further investigate the inhibition mechanism.…”
