摘要

Stainless steels have been used extensively in various fields while corrosion can brought seriousproblems to their functionality. The inhibition effect of 6-dibutylamino-1,3,5-triazine-2,4-dithiolmonosodium (DBN) on SUS304 stainless steel corrosion in 1.0 M HCl was studied by means ofelectrochemical impedance spectroscopy (EIS), potentiodynamic polarization, cyclic voltammeter (CV)and scanning electron microscopy (SEM) techniques. Results from electrochemical measurementsshowed that the corrosion inhibition performance of DBN was effective, and the protection efficiencywas up to 99.82%. Adsorption of DBN inhibitors on stainless steel surface followed Langmuir’sadsorption isotherm at 30 °C. Further, morphology observation suggested that the stainless steel waswell protected by DBN inhibitor.
