The effects of rotational speed and sand concentrations on the wear behavior on carbon steel and stainlesssteel were investigated by open-circuit potential, polarization curves, electrochemical impedancespectroscopy and scanning electron microscopy. The mass loss rates of samples under each conditionwere determined. The erosion rates of both steels increased with the rotational speed and sandconcentration, and the erosion rates of the 304 stainless steel were approximately one-tenth of the carbonsteel for the same conditions in the sand-containing water. The erosion rate that was calculated from thepolarization curve method was similar to the tested mass loss results, and can be used to determine theerosion rate in flowing sand-containing water.
