Single particle impingement current transients for prediction of erosion-enhanced corrosion on 304 stainless steel
چکیده انگلیسی

A new device was used to study the characteristics of a single particle impact on the surface of stainless steel. Maximum depassivation occurred at 30° where nearly 30% of the scar area was depassivated. The kinetics of particles motion and electrochemical response of the surface were correlated. The predicted erosion-enhanced corrosion current under slurry flow conditions based on the correlation reasonably matched the experimental results at lower sand concentrations. The predicted currents deviated from experimental values at higher sand concentrations where interactions between particles before and after impact are not negligible.
