| Abstract Scope |
In the present study, interactive corrosion between International Simple Glass (ISG) and Stainless Steel 316 (SS) has been studied by exposing sandwiched coupons of these materials in different solutions at 90oC. Solution analyses and cross-section morphologies indicate a higher dissolution of ISG in the presence of SS. The chemical composition of the glass alteration layer depends on the local solution chemistry, which in turn is affected by the localized corrosion of SS. Infrared spectroscopy results indicate structural reorganization of the silicate alteration layer. On the other hand, localized corrosion of SS in contact with ISG is aggravated in the presence of Cl- in solution, which is known to be aggressive to corrosion resistant alloys. Metal cations from stainless steel dissolution precipitate with SiO2 from solution on the ISG and SS surface resulting in enhanced dissolution of ISG. |
