Abstract Pourbaix diagrams (potential-pH diagrams) for the ternary system of Fe-Cr-Ni at 25°C to °C were calculated. Extrapolation of thermochemical data to elevated temperatures was performed with the revised model of Helgeson-Kirkham-Flowers, which also .
In electrochemistry, a Pourbaix diagram, also known as a potential/pH diagram, E H-pH diagram or a pE/pH diagram, maps out possible stable (equilibrium) phases of an aqueous electrochemical system. Predominant ion boundaries are represented by lines.
In an Eh-pH diagram, the solid stability area is related to the saturation condition, The most well-known studies on comprehensive Eh-pH diagrams are those of Pourbaix () and Brookins (). The former discussed corrosion, passivation and immunity of materials, while the. Nickel Pourbaix diagram at °C, 25 MPa and 10 −8 mol/kg.
Comparing Fig. 10a to Fig.
9a (both at 10 −6 mol/kg) reveals the diagrams are similar but the bunsenite stability region is slightly larger at the higher temperature and pressure.Pourbaix diagram - WikipediaDiagram: Pourbaix Diagram Nickel
