Abstract The anodic polarization curves of stainless steel CIS in aqueous solution of 20wt% H2SO4 were measured under superimposition of a range of alternating current from 0mA/cm2 to 20mA/cm2. It was found that the presence of A.C. altered the corrosion potential, enhanced the active-passive peak, increased the dissolution current density in the passive region and shifted the passive-transpassive potential towards the negative direction. When the alternating current density was not more than 20mA/cm2, a wide passivation region remained.

Key words: Stainless steel Alternating current corrosion Anodic polarization
