Abstract
The phase diagram of the Ni-Mo-O system and the potential-pH diagram of the Ni-Mo-H2O system at 25°C are composed. The electrochemical equilibrium diagram of a NiCr15Mo15 alloy (70%Ni + 15%Mo + 15%Cr) at the standard temperature is refined. The beneficial effect of molybdenum on the stability of the alloys’ passive state is discussed in terms of thermodynamics.
