A Rapid Investigation on the Initiation of Crevice Corrosion for 1Cr13 Stainless Steel in 3.5% NaCl Solution
-
摘要: 本文通過對帶縫試樣施加小幅值恒定陽極極化電流的方法,人為地突出了縫隙微區的影響和作用,為尋求一種既能縮短縫隙腐蝕研究周期,又能較少地干攏腐蝕體系自身反應的實驗技術進行了初步的嘗試。實驗結果表明,不銹鋼鈍化膜表面的性質與縫內溶液的狀態是影響縫隙腐蝕誘發過程的兩個重要因素。Abstract: 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.
