| Abstract: | Inhibiting performance of several corrosion inhibitors for TU42C steel in sulfuric acidic solution was studied by weight loss test and electrochemical measurement and their inhibiting mechanism was discussed. Results showed that inhibiting efficiency was in order: Lan-826>Changcheng 3 #>Ruoding. The optimum concentration of Lan-826, Changcheng 3 # and Ruoding was 0.3%, 0.3% and 0.4% respectively. The polarization curves showed that Lan-826, Changcheng 3 # and Ruoding belonged to mixed type inhibitor. |
