Paper Title:
Inhibition Behavior of a Novel Acidification Inhibitor for Steels at High Temperature
  Abstract

The QL-03 corrosion inhibition system is obtained by the compounds of quinoline quaternary ammonium salt,mannich base and synergist. The mechanism of QL-03 with HP13Cr in 20%HCl is investigated by potentiodynamic polarization curves, EIS and weight loss measurements. The results show that the inhibition efficiency towards HP13Cr steel is improved greatly and reaches as high as 90% at 90°C, as a mixed corrosion inhibition system. Cumulating the inhibition efficiency from electrochemical results is more reasonable than weight loss result.
