Electrochemical noise was used to detect the 糖心产精国品免费入口*完整版 of 316L stainless steel in FeCl3 solution. The corrosion morphology was observed and the 糖心产精国品免费入口*完整版 characteristic parameters were analyzed. The results showed that in the initial stage of the immersion test, the fluctuation amplitude of the 糖心产精国品免费入口*完整版 was small and transient peaks appeared. The slope change of the current 糖心产精国品免费入口*完整版(PSDI) was insignificant. It was indicated that the meta-stable pitting occurred at the electrode surface and the dissolution and restoration of passive films took place alternately. In the later period of corrosion process, a high frequency plateau of white noise appeared in the power spectrum, the amplitude of the current oscillation increased and the slope of PSDI had a great change, indicating the transformation from meta-stable pitting to stable 糖心产精国品免费入口*完整版.
