Abstract The surface differentials of stainless steel in dif ferent NaCl consistence solutions were measured using wire beam electrodes (WBE) as reference or supporting electrodes.It was found that the data-ranges measure d by WBE for items of potentials or galvanic currents or Faraday impedance had g ood linear relationship with logarithm of NaCl concentrations.They had superiori ty as the indexes of materials pitting sensitivity than the traditional indexes such as,the pitting potential,the lag ring area in scan anodic polarization curv es and so on.In additions,the pitting latent periods of materials could be also studied by WBE based on the curves of potential ranges vs.time in natural immers ion tests.
