| The work aims to obtain 3-amino-1, 2, 4-triazole and 3-amino-1, 2, 4-triazole and three kinds of self-assembled films of triazol-3-ylamine and three kinds of aldehydes Schiff base, and increase corrosion inhibition of carbon steel in 0.5 mol/L HCl solution. Electrochemical parameters of Schiff base self-assembled films in HCl solution, such as impedance variation, corrosion potential and corrosion current, were studied by using electrochemical impedance spectroscopy, tafel polarization curve, etc. Composition of the self-assembled films was characterized by using XPS. The maximum inhibition efficiency of self-assembled films was up to 92.72% in HCl solution, XPS test showed that self-assembled molecules and metallic atoms bonded in the form of chemical. The 3-amino-1, 2, 4-triazole and 3-amino-1, 2, 4-triazole aromatic aldehydes Schiff bases provide favorable corrosion inhibition effect for carbon steel in HCl. The inhibiting efficiency depends on the molecular structure, O and N heteroatoms, halogen group, three thiazole ring and benzene ring contribute to the formation of self-assembled films. |
