Abstract The corrosion behavior of pipeline steel under the combined action of the applied alternating stray current and cathodic protection was assessed via a home-made stray current corrosion testing device, mass loss measurement and electrochemical methods. The results show that with the increase of AC current density, the corrosion potential of pipeline steel is negatively shifted and the metal corrosion tendency is enhanced. AC interference promotes the anodic oxidation reaction in the positive half cycle of AC and then increases the corrosion rate of pipeline steel. With the increase of AC frequency, the corrosion process of the pipeline steel is shortened for each cycle of AC, the Faraday current, as promoter for metal oxidation reaction is suppressed, therewith the corrosion rate of pipeline steel is reduced. The corrosion rate of pipeline steel increases in strong acid or alkali environment.
