WebAn Atlas of Electrochemical Equilibria has been created by M. Pourbaix for metals in aqueous solution at room temperature. 18 This atlas contains potential-pH diagrams, so-called Pourbaix diagrams, which define three equilibrium thermodynamic domains for metals in aqueous solutions: immunity, passivity, and corrosion.Immunity is defined as … WebPourbaix diagrams for the copper-chlorine system have been published by Pourbaix (1945) and Duby (1977). Pourbaix diagrams for the copper-chloride system have been reported by Mattsson (1962), Pourbaix (1973), Skrifvars (1993), Ahonen (1995), and Nila and Gonzalez (1996). Only Ahonen presented diagrams for elevated temperatures (100 …
