Abstract
Ni100-xFex metallic glasses have been prepared with 8.5 less than or equal to x less than or equal to 51 using electrodeposition technique. Corrosion behavior of specimens in 0.1 M Na2SO4 (pH = 6) at 25 degrees C has been stu died using potential-time decay, linear polarization resistance and potenti odynamic techniques. Anodic polarization curves show that the specimens exh ibit quasi-passive region. The dissolution of samples increases with the in crease of iron concentration and also with the increase of annealing temper ature. The interpretation was based on the enhanced dissolution of the form ed microcrystals of the specimens in the sulphate solution. (C) 1999 Kluwer Academic Publishers.
