Abstract  Simulated occluded corrosion cell(OCC) was used to stud y the changes of chemical state within the OCC of 304 stainless steel in neutra l solution of 0.5 mol/L NaCl containing various SDS(sodium dodecyl sulphate) ion concentration at 50℃.Anodic polarizing occluded specimen to simulate reaction current between outer and inter of OCC.It was found that,when C12H25 SO-4 anion added into the bulk solution,it migrated into OCC,and the migrati on quantity increased with the concentration and the time,the migration rate dec reased with the length of the time.C12H25SO-4 was in competition with Cl- on migration,It can retard the migration of Cl- effectively above a certain concentration,The higher the concentration,the more the efficiency.C 12H25SO-4 can not retard pH fall but fell multiples of Cl- enric hment effectively above a certain concentration.SDS was anioning inhibitor,E b and Ep were shifted towards positive potentials by the addition of C 12H25SO-4,indicating suppression of pit propagation.
