Amorphous alloys chemical homogeneity

Beside the beneficial effect of the addition alloying metallic elements that contribute to the increased corrosion resistance, the amorphous structure itself is also responsible for the very low corrosion. For example, crystalline alloys with the same composition exhibit high rates of dissolution. The chemically homogeneous, single-phase nature of amorphous alloys is believed to account for their corrosion resistance (8, 100, 101). This also allows for the formation of a uniform, protective film on the surface of amorphous alloy electrodes. 

Ideally, an amorphous metal alloy should be chemically and structurally isotropic. Isotropic surfaces would be ideal for catalytic applications, since any structural and chemical heterogeneity can impede the selectivity with which a particular chemical reaction is catalyzed. However, several studies [4.18,50,57-59] reveal that the surface of glassy metals prepared by meltspinning may not be as homogeneous as expected. Structural as well as chemical...
