Thetests were interrupted on schedule to make plastic replica of corroded specimen surfaceon which many randomly distributed pits can be found. The development of the geometricparameters of pits was obtained and the statistical distributions of these parameterswere determined. Instead of depth, the ratio of depth to width is the most domi-nant parameter in relation to crack initiation. Also, the pitting was enhanced whenlow frequency or high stress range was applied and although stress range has noeffect on the nucleation of pits, it can accelerate the initiation of cracks from pits.
