摘要：The effects of sensitization on the metastable pitting behaviour of 304 stainless steel in 3.5 wt.% NaCl solution were investigated via electrochemical measurements and microscopic observations. Results showed that sensitization decreased pitting potential and slightly affected metastable pitting potential. Sensitization treatment increased the nucleation frequency of metastable pitting, promoted its propagation and changed the shape of current transients. The results of scanning electron microscopy and energy-dispersive X-ray spectroscopy showed that metastable pitting was initiated at MnS inclusions for the solution-treated and sensitized samples. The combined effects of the passive film and inclusions were considered to play a vital role on the metastable pitting behaviour.
