Abstract
Transition from passivation to erosion-corrosion at the critical flow velocity (CFV) is of interest for corrosion engineers. This transition phenomenon on 304 stainless steel and a Fe-based amorphous coating was investigated under impingement by sand-containing NaCl solution. Mass loss measurement, open-circuit potential monitoring and potentiostatic test were employed to determine the CFV. The CFV values defined via the three approaches are consistent, about 10. m/s for 304 stainless steel and 15. m/s for the coating. The CFV decreases with increasing the sand concentration. It may serve as an effective tool for evaluating the erosion-corrosion resistance of passive materials.
