Corrosion details can be accessed by clicking button “Show details” in the FREECORP data window. This feature gives a tabulation of all involved corrosive species in terms of their contributions to overall corrosion rate expressed in percentage.
For CO₂ corrosion, the values are obtained based on cathodic current densities of the corrosive species and shown as percentages (see figure). This example shows that in corrosion of 1.98 mm/year pH contributes 45%, CO2 contributes 37.51 %, H₂O contributes .2% and HAc contributes 16.45%.

For H₂S corrosion, the values are calculated based on fluxes of corrosive species and shown as percentages (see figure). The example shows that H₂S contributes 18.37%, pH contributes 41.06%, CO₂ contributes 25.58%, and HAc contributes 14.99% to overall corrosion of 0.175 mm/year.
