摘要：

The role of electrode potential change on the stability of crevice corrosion in stainless steel, AISI 316 (UNS S31600), was investigated in 3% sodium chloride (NaCl) at 80degreesC. The distribution of the crevice corrosion rate over the crevice surface was monitored and recorded using the Moire technique. The crevice was an artificial clear glass/metal crevice with a gap thickness of 5 mm. Experimentation demonstrated that for applied potentials greater than the repassivation potential for crevice corrosion (E-R,E-CRV), a more noble potential resulted in a more stable crevice corrosion.
