The effect of sinusoidal current on the corrosion of mild steel in aqueous solution has been examined with an alternating voltage (AV) modulation method. It was found that AV shifted the corrosion potential toward the negative direction, increased dissolution current density in the active region, and destroyed the passivity of mild steel at the passive potentials. The effect of AV was simulated numerically with a charge‐transfer reaction model, and the calculated polarization curves showed the characteristics similar to those of the experimental curves.
