What is it about?
Chemical stability diagrams (CSDs) were originally devised by Marcel Pourbaix, but have been underutilized over the past 70 years in the field of electrochemistry. This work develops new additions to the CSD method to enable (1) the thermodynamic solution chemistry trajectory from an initial condition, (2) the incorporation of buffering effects in the bulk environment, and (3) the consideration of alloyed substrates. These developments widen the predictive capability of the CSD method for experimental design and analysis.

Why is it important?
This thermodynamic prediction method can save researchers considerable time and effort. These accessible calculations based on open source activity and/or solubility data predict electrochemical test results in terms of severity of corrosion, solid oxidation product formation, as well as critical species concentrations/thresholds. Thus, CSDs should be used to purposefully construct experiments as well as to interpret their results, which will assist researchers to deviate from empirical methods.
