| dc.description.abstract | This paper presents results from AC corrosion tests on 25Cr duplex and cathodically protected carbon steel. The results show that the corrosion rate is independent of transfer current density (0-200 A/m2) and power frequency (50-200 Hz) on cathodically protected carbon steel. On the anodes (AlZnIn), the corrosion rate increases as a function of transfer current density (0-80 A/m2). However, the correlation is less prominent at higher frequencies (100-200 Hz). For the freely corroding super duplex, the correlation is similar to that on the anodes for the highest current density (1000 A/m2). For the lowest current densities (100 A/m2), the corrosion rate was independent of power frequency. Safe levels for AC induced transfer current densities are proposed at power frequencies of 50, 100 and 200 Hz.
