Triazole derivatives as corrosion inhibitors for mild steel in hydrochloric acid solution
Keywords: Materials protection,Acid inhibitor,Triazole-type compound Abstract: The title compounds 1-(4,5-dihydro-3-phenyl pyridine-1-yl)-2-(1H-1,2,4-triazole-1-yl)ethyl ketones were studied as a corrosion inhibitor in a mild steel in 1 mol /L hy-drochloric acid solution using weight loss measurement,potentiodynamic polariza-tion,and electrochemical impedance spectroscopy(EIS).Results indicated that these compounds had excellent inhibition properties.Polarization curves indicated that the inhibitor behaved mainly as mixed-type inhibitor.The EIS results showed that the charge transfer ...
