Abstract
The corrosion behaviour of melt spun amorphous and nanoquasicrystalline Zr70Pd30 and Zr80Pt20 alloy ribbons has been investigated using potentiodynamic polarization study in NaCl, H2SO4 and NaOH solutions at different concentrations. The amorphous and nanoquasicrystalline alloys show better corrosion resistance than Zr in all the solutions studied. Both the alloys are susceptible to chloride attack and pitting has been observed. Complete passivation has been observed in H2SO4, while gradual break down of passivating layer occurs in NaOH. In general, nanoquasicrystalline state in both the alloys shows better corrosion resistance than amorphous state in all the solutions studied.
