2-氨基嘧啶在盐酸介质中对钢的缓蚀性能
Corrosion Inhibition of 2-Aminopyrimidine for Steel in Hydrochloric Acid Media
摘要
Abstract
The inhibition effect of 2-aminopyrimidine(2-AP) on the corrosion of cold rolled steel (CRS) in 1. 0 ~5. 0 mol/L HCI media at 20 ~50 ℃ has been studied by mass loss, potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) methods. The results showed that the neutral 2-AP is a good inhibitor for CRS, and the adsorption of 2-AP on the CRS surface follows the amended Langmuir adsorption isotherm equation. Inhibition efficiency increases with the inhibitor concentration, while decreases with temperature and the concentration of HC1. Polarization curves showed that 2-AP is a mixed-type inhibitor. EIS spectra exhibited one capacitive loop, and the charge transfer resistance increased with the inhibitor 2-AP concentration.关键词
