Abstract

The inhibition performance of two compounds of benzimidazole N-mannich base namely PAB and PPB for N80 steel in HCl solution was investigated by means of weight loss test, potentiodynamic polarization and electrochemical impedance spectroscopy. The results showed that both PAB and PPB were mixed-type inhibitor, and were adsorbed on the surface of mild steel spontaneously; whilst PPB has higher inhibition efficiency than that of PAB, which accorded well with theoretical prediction. Furthermore,the adsorption of both PAB and PPB follows Langmuir isotherm law.

Key words: benzimidazol derivative corrosion inhibitor electrochemical measurement quantum chemistry calculation molecular dynamics simulation
