| Abstract: |
| The corrosion inhibition action of imidazole, 1-dodecylimidazole, 1-benzylimidazole, benzimidazole self-assembled films for 316 stainless steel in 0 . 5 mol / L H2SO4solution was investigated by electrochemical impedance spectroscopy,polarization curves and quantum chemical calculations. Results showed that four inhibitors were all cathodic inhibitors and performed pretty inhibiting efficiency for 316 stainless steel . As the concentration of inhibitors were 1 X10-3mol / L,the longer the assembled time,the better the effect of inhibition. The inhibition efficiency of the four inhibitors was up to the value of EHOMO. The inhibition efficiency of the four inhibitors decreased as follows:benzimidazole>1-dodecylimidazole>1-benzylimidazole> imidazole. |
