- Abstract:
- Stainless steel often germinates in Cl-containing solutions with porous lacy cover etched holes, and continuous erosion is hidden on the inner surface of the pit under the lace cover, which is an interesting pitting corrosion that often aggravates the failure of the material. Fine 316 ss microelectrode area regulation was used to form a single pitting hole to study pitting corrosion, and the kinetic data of pitting corrosion development were obtained, and according to Fick’s diffusion law, it can be seen that the stable growth condition of pitting corrosion is the product of current density (i) and depth (a) in the pit. The effect of lace cover on the growth of metastable pitting was confirmed by a new ultrasonic electrolytic cell.
