چکیده مقاله
In this work, the adsorption and corrosion inhibition effect of two new synthesized
compounds on mild steel in 6M hydrochloric acid was studied by electrochemical
impedance spectroscopy, Tafel polarization, weight loss, quantum, and atomic force
microscopy methods. The obtained results show that these compounds are efficient
corrosion inhibitors for mild steel in hydrochloric acid media. Electrochemical impedance
spectroscopy shows that inhibition efficiency increases with increase of
concentration of both inhibitors. These molecules obey the Langmuir adsorption isotherm.
Some samples of mild steel were examined by atomic force microscopy.
Quantum chemical calculations were further applied to reveal the adsorption structure
and explain the experimental results.
