| Summary: | Abstract This work presents a new and efficient biobased hybrid hinge based on lanthanum (La) cations and trigonella grandiflora (TG) extract, represented as La@TG, in a 3.5% NaCl solution, as an organic/inorganic mild steel corrosion inhibitor. The concentration of La cations and TG components released into the solution at various pH levels was assessed using UV-Vis/ICP-OES analysis. The composition and morphology of the adsorbed film were characterized using analytical techniques such as atomic force microscopy (AFM), Fourier-transform infrared spectroscopy (FTIR), energy-dispersive spectroscopy combined with scanning electron microscopy (SEM-EDS), and grazing incidence X-ray diffraction (GI-XRD) on the submerged electrode. Electrochemical techniques were leveraged to examine the effectiveness of the La@TG hybrid and to understand its inhibition mechanism in both solution and coating (intact and scratched) phases. The electrochemical analyses in the solution phase revealed that the La@TG hybrid exhibits relatively good corrosion resistance. Additionally, in the presence of an artificial flaw, the epoxy coating containing the La@TG hybrid showed strong active/barrier protection with self-healing qualities. |
