| Abstract: | A new corrosion inhibitor of triazole-type compound 1-phenylacetimino-2-mercapto-5-[1'-(1',3',4'-triazolyl)-methene]-1,3,4-triazoles(PMT) has been synthesized and its inhibiting action on the corrosion of Q235 steel in 0.5 mol/L H2SO4 has been investigated by weight loss measurements,potentiodynamic polarization,electrochemical impedance spectroscopy(EIS) and scanning electronic microscopy(SEM).The PMT showed very excellent inhibition performance and behaved as a mixed-type inhibitor. |
| Keywords: | Triazole-type compound Corrosion inhibitor Weight loss measurement Potentiodynamic polarization Electrochemical impendence spectroscopy |
