摘要：
The inhibition effect of triazolyl blue tetrazolium bromide (TBTB) on the corrosion of cold rolled steel (CRS) in 1 0 M HCl and 05 M H2SO4 solution was investigated for the first time by weight loss potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) methods The results show that TBTB is a very good inhibitor and is more efficiency in 1 0 M HCl than 0 5 M H2SO4 The adsorption of TBTB on CRS surface obeys Langmuir adsorption isotherm Polarization curves reveal that TBTB acts as a mixed-type inhibitor in both acids (C) 2010 Elsevier Ltd All rights reserved
