Study of surface irregularity on corrosion of steel in alkaline media

摘要

In this study, the effects of the surface condition of rebar on its cathodic current efficiency were investigated. The cathodic current efficiencies for rebar with different surface conditions were determined from cyclic polarization experiments. The results showed that cathodic faradaic current increased with surface irregularity. Surface condition of steel in alkaline solution also had an effect on double-layer capacitance.
