Abstract:

The resistance of four crown-and-bridge alloys to halide attack was assessed. In aerated medium, the equilibrium behavior of two gold containing alloys was characterized by passivity, whereas that of two materials of lesser nobility was typified by active dissolution. Corrosion rates of the test alloys were accelerated in oxygen depleted medium. In deaerated solvent, the passive equilibrium condition was experienced only by a nickel-chromium based alloy. Author
