Hydrogen permeability of Pd-coated Ni60Nb15Ti15Zr10 and Ni60Nb20Ti15Zr5 amorphous alloys was measured at 673 to 773K and was compared with the results obtained using Ni60Nb40, a binary amorphous alloy. The permeability 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 16.6h.
