Abstract

Ni100−xFex metallic glasses have been prepared with 8.5 ≤ x ≤ 51 using electrodeposition technique. Corrosion behavior of specimens in 0.1 M Na2SO4 (pH = 6) at 25°C has been studied using potential-time decay, linear polarization resistance and potentiodynamic techniques. Anodic polarization curves show that the specimens exhibit quasi-passive region. The dissolution of samples increases with the increase of iron concentration and also with the increase of annealing temperature. The interpretation was based on the enhanced dissolution of the formed microcrystals of the specimens in the sulphate solution.
