Abstract
Erosion-enhanced corrosion of carbon steel in passive state during slurry impingement is dominated by the competition between fresh surface generation and repassivation. The presence of chloride retards repassivation. The average corrosion rate is quantitatively predictable when the hydrodynamics of slurry and repassivation kinetics of target material are known. The electrochemical impedance spectroscopy suggests that the corrosion in flowing slurry is under mixed control of interface charge transfer and mass transport. The later becomes the dominative role gradually with increasing generation rate of fresh surface. Slurry impingement may facilitate pit formation and promote repassivation of existing pits simultaneously.
