Corrosion Analyzer uses a first principles thermodynamic model to compute the composition of the near-surface liquid and a multi-functional rate expression to compute corrosion rates. Both the thermodynamic model and the corrosion rate expression are validated using peer-reviewed experimental data. This ensures that the software delivers accuratepredictions across a broad range of operating conditions.
