Received February 27, 2006 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. PACS numbers: 81.65.Kn DOI: 10.1134/S2070205109030149
