摘要：
With the use of the substitution solution model, thermodynamic properties of Cu-Ni solid solutions are described in the stratification region. Cross sections of the Cu-Ni-O phase diagram and potentialpH diagrams of the German silver-H2O systems, such as CuNi19-H2O and MNZhMts30-1-1-H2O, at 25°C and 1 bar are plotted. The homogeneity region of NiOx phase at equilibrium with atmospheric oxygen is estimated at various temperatures. Thermodynamic features of the corrosion-electrochemical behavior of copper-nickel alloys are analyzed.
