A Rapid Investigation on the Initiation of Crevice Corrosion for 1Cr13 Stainless Steel in 3.5% NaCl Solution

The resistance of 1 r13 stainless steel to crevice corrosion in 3.5% Nacl solution has been studied by the galvanostatic method, using acrevice assembly By analysis of the time dependence of potential, the rapid research on the initiation of crevice corrosion has been performed.The results indicate that the inhomogencity of the passive film and the conditions of solution within the crevice have a great effect on the initiation of crevice corrosion.
