Hydrogen Permeation Properties of Pd-Coated Ni-Nb-Ti-Zr Amorphous Alloys

Abstract

Hydrogen permeability of Pd-coated Ni60Nb15Ti15Zr10 and Ni60Nb20Ti15Zr5 amorphous alloys was measured in the temperature range of 673 K to 773 K and was compared with the results obtained using Ni60Nb40, a binary amorphous alloy. The pen-neability thus measured was found to increase moderately increasing temperature. A long-term permeation test for the Pd-coated Ni60Nb15Ti15Zr10 amorphous alloy revealed high permeation stability up to 16.6 h.
