Corrosion Analyzer The Corrosion Analyzer contains the key features of OLI's corrosion technology, including: Real Solution Pourbaix Diagrams Graphical depiction of EH vs. pH for any mixture of chemicals in water or mixed solvents is available to evaluate stable and metastable corrosion and redox products. Real-solution chemistry is used at actual operating conditions, accounting for all activity coefficients, and assessing the effect of passivating species without any simplifying assumptions. Alloy support is virtually unlimited for Fe-Cr-Ni-Mo-C-N and Cu-Ni alloys. Stability Diagrams Flexible selection of independent variables and graphical depiction of local and global equilibria in various projections are available. Depictions include EH vs. composition and composition vs. pH for any chemical mixture, including trace components, to assess stable and metastable species in real solutions. Localized corrosion indicator The corrosion and repassivation potentials are calculated. In regions where the corrosion potential is larger than the repassivation potential for pitting, localized corrosion will occur. |
Polarization curves Calculations and display of polarization curves is the key to OLI’s kinetic model for generalized corrosion. The polarization curves show the rate at which the reactions at the metal surface are proceeding. Each partial anodic and cathodic process is predicted. The sum of all the reactions results in the net current, or polarization curve.
