Amorphous alloys possess better corrosion resistance than crystalline alloys because these are devoid of defects present in a crystalline lattice and are compositionally more homogeneous. The conclusions drawn by the authors are as follows: (1) Corrosion behavior of rapidly solidified Zr[sub 76]Ni[sub 16]Fe[sub 8] alloy ribbon varies across its thickness in chloride environments. (2) Wheel side surface of the ribbon (fully amorphous structure) possesses better corrosion resistance than the air side surface of the ribbon (partial crystallinity) in the chloride environments. (3) Among the three factors, namely, partial crystallinity, air pockets and compositional difference induced in rapidly solidified Zr[sub 76]Ni[sub 16]Fe[sub 8] alloy ribbon, partial crystallinity appears to be the most harmful as far its corrosion resistance in chloride environments is concerned.
