“…This is due to that the adsorption/desorption of inhibitor molecules on the metal surface is a thermodynamic equilibrium process, and the high temperature will promote the desorption of inhibitor molecules on the metal surface, decreasing the surface coverage of the inhibitor, thus leading to boosting the corrosion .

Corrosion protection of metal has become an important and urgent topic, which requires the development of an inexpensive, environmentally friendly, and highly efficient corrosion inhibitor. Herein, a sweet potato leaf extract (SPL) was obtained by a simple water-based extraction method and then as a green corrosion inhibitor for 6N01 Al alloy in the seawater was well investigated by the weight loss method and various electrochemical tests. Fourier transform infrared (FT-IR) and ultraviolet−visible (UV−vis) spectroscopies were carried out to investigate the compositions of SPL. The findings from the potentiodynamic polarization (PDP) curves suggest that SPL functions as a typical mixed-type corrosion inhibitor. Notably, the maximum corrosion inhibition efficiency reaches 94.6% following a 36 h immersion period at 25 °C. The adsorption behavior of SPL on the Al alloy surface belongs to the Langmuir adsorption isotherm. The Gibbs free energy value illustrates that the adsorption of SPL contains both physisorption and chemisorption. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) indicate that SPL is firmly attached to the Al alloy surface by making a protective layer, which can effectively inhibit the corrosion of the Al alloy in the seawater. Furthermore, quantum chemical calculations were applied to validate the chemical adsorption and elucidate the relationship between the electronic structure of the active components in SPL and their effectiveness in corrosion inhibition.

“…Table 5 reports the Δ G ° ads results obtained for the PILs poly[VIMC4][Im], poly[VIMC2][Br], and poly[VIMC4][Br] at 25 °C. The negative values of Δ G ° ads indicate that the adsorption of the CIs was thermodynamically spontaneous 69 and suggest that a physicochemical adsorption process started through electrostatic forces between the steel surface and N heteroatoms present in the PILs such as vinylpyrrolidone, acrylamide, vinyl alkylimidazolium [VIM + ] cations, imidazolate [Im – ] anions, and bromides [Br – ]. In addition, chemisorption-coordinated complexes can be formed 70 between the present IL species like vinylalkylimidazolium bromide or vinylbutyl imidazolium imidazolate and the vacant Fe d orbital on the metal surface.…”

A corrosion inhibition mechanism of API 5L X60 steel exposed to 1.0 M H 2 SO 4 was proposed from the evaluation of three vinylalkylimidazolium poly(ionic liquids) (PILs), employing electrochemical and surface analysis techniques. The synthesized PILs were classified as mixed-type inhibitors whose surface adsorption was promoted mainly by bromide and imidazolate ions, which along with vinylimidazolium cations exerted a resistive effect driven by a charge transfer process by means of a protective PIL film with maximal efficiency of 85% at 175 ppm; the steel surface displayed less surface damage due to the formation of metal−PIL complex compounds.

“…The excellent corrosion inhibition property of inhibitors was linked to the presence of tertiary amine groups which effectively bound with Fe. The corrosion inhibitor N1-(2-aminoethyl)-N2-(2-(2-(furan-2-yl)-4,5-dihydro-1H-imidazol-1-yl) ethyl) ethane-1,2-diamine (NNED) showed excellent corrosion inhibitive action for carbon steel in 1 M HCl [23]. It exhibited more than 90% corrosion inhibition efficiency at 5 ppm.…”

Metal corrosion constitutes degradation of metals in the presence of favorable corrosive atmosphere. It worsens metal quality. The prevention of metal corrosion is so significant to save metals for their better utility. Corrosion inhibitors are widely used for the mitigation of metal corrosion. Small organic molecules as corrosion inhibitors are showed prominent corrosion inhibitive property because of their unique electron donating capacity to the metal orbitals. The bonding occurred between organic molecules and metals are main aspect to retard the corrosive environment toward metal.
