Abstract

The corrosion behavior of CoCrFeNiMo _x alloys was investigated in aqueous environments, NaCl and H ₂ SO ₄ solutions, respectively, to simulate typical neutral and acidic conditions. The cyclic polarization curves in NaCl and the potentiodynamic curves in H ₂ SO ₄ clearly reveal the beneficial effects of Mo and the detrimental effect of σ-phase on the corrosion resistance. The X-ray photoelectron spectroscopy results of CoCrFeNiMo _x alloys in H ₂ SO ₄ solution indicate that Cr and Mo predominate the corroded surface of the alloys, where Mo primarily exists in the form of MoO ₃ .
