Construction of Pourbaix Diagrams for Alloy Systems with Special Application to the Binary Fe-Cr System
Abstract
Using potentiokinetic techniques with the electrochemical hysteresis method, experimental Pourbaix Diagrams were constructed for a series of six binary Fe-Cr alloys ranging in chromium content from 0.5% to 24.9%. Thirty-six solution variables were employed which included pHs from 4.5 to 11 inclusive and chloride contents from nil to saturated at room temperature. In addition to establishing domains of non-corrosion, general corrosion and passivation, the loci of zero current potentials, pitting potentials and protection potentials were determined as a function of pH, chloride ion concentration and chromium content. Corrosion velocities were determined for each region of the experimental diagrams.
