不锈钢缝隙腐蚀诱发过程的快速研究

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

    摘要
  • 摘要: 本文通过对带缝试样施加小幅值恒定阳极极化电流的方法,人为地突出了缝隙微区的影响和作用,为寻求一种既能缩短缝隙腐蚀研究周期,又能较少地干拢腐蚀体系自身反应的实验技术进行了初步的尝试。实验结果表明,不锈钢钝化膜表面的性质与缝内溶液的状态是影响缝隙腐蚀诱发过程的两个重要因素。

     

    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.
