Objective To study the inhibition behavior and the optimal composition of CP-CI021 pre-filmed inhibitor for Q235 steel in seawater. Methods The inhibition behavior of CP-CI021 for Q235 steel in seawater and the optimal composition were investigated with weight loss method and electrochemical impedance spectroscopy. Results The CP-CI021 pre-filmed inhibitor had excellent inhibition property, and the EIS impedance modulus of pre-filmed Q235 steel increased by 2 orders of magnitude compared to the Q235 steel without pre-filming. Conclusion The optimal composition of CP-CI021 pre-filmed inhibitor was: PHA, 7.3 g/L, assistant A, 3 g/L, assistant B, 5 g/L, and the inhibition efficiency reached 98.4%. |
