Five non-precious Ni-Co based alloys were analyzed with respect to their corrosion behaviour. The correlation between the amount of the elements Cr, Mo, V and the corrosion behaviour, expressed by the PREN (pitting resistance equivalent number) index in the case of the allied steels, was extended for Ni-Cr and Co-Cr dental alloys characterization.

The potentiodynamic polarization methods have been employed to evaluate the corrosion resistance of the Gaudent-S dental alloy in a slightly acid artificial saliva (Fusayama's saliva; pH = 6.18), a slightly alkaline artificial saliva (Rondelli's saliva; pH = 7.75) and in an acid saline solution (NaCl/lactic acid; pH = 2.64). The results were compared with(More)
