The effects of ozonated seawater on the corrosion behavior of nickel-chromiummolybdenum alloys C-276, C-22, 625 and 59 (UNS N10276, N06022, N06625, and N06059) were studied and the results were compared with those obtained for aerated solutions. Corrosion rates and crevice corrosion information obtained from plate samples at intervals of 2, 4, 8, 16, 26, and 47 weeks were compared with electrochemical measurements of corrosion potential, linear polarization resistance (LPR), and cyclic polarization curves from concurrently immersed wire samples. It was observed that samples in ozonated seawater, in general, exhibited higher corrosion rates...
