Abstract
The corrosion behavior of melt-spun amorphous and nanoquasicrystalline Zr80Pt20 ribbons and amorphous Zr70Pd30 ribbons has been investigated using a potentiodynamic polarization study in a neutral NaCl solution. All three alloys are susceptible to chloride attack, and pitting is observed. The pitting corrosion behavior of these alloys has been compared with zirconium (98% pure). The oxidation behavior of the amorphous Zr70Pd30 alloy and the partially nanocrystalline Zr80Pt20 alloys has been studied non-isothermally by a thermo-gravimetric analysis in static air at different heating rates up to 773 K. It was observed that the amorphous Zr70Pd30 alloy readily oxidizes. Zr80Pt20 alloys in the nanoquasicrystalline state are more resistant to oxidation.
