Hydrogen Permeation Properties of Pd-Coated Ni(37.5)Nb(27.5)Zr(25)Co(5)Ta(5) Amorphous Membrane

Hydrogen Permeation Properties of Pd-Coated Ni(37.5)Nb(27.5)Zr(25)Co(5)Ta(5) Amorphous Membrane

The hydrogen permeation properties of the Pd-coated Ni(37.5)Nb(27.5)Zr(25)Co(5)Ta(5) amorphous membranes have been investigated at 673 and 723K for 720 hours (1 month). Values of the hydrogen permeability during these long term tests were found to be reduced of about 50 and 30% at 673 and 723K, resp...

Zusammenfassung:The hydrogen permeation properties of the Pd-coated Ni(37.5)Nb(27.5)Zr(25)Co(5)Ta(5) amorphous membranes have been investigated at 673 and 723K for 720 hours (1 month). Values of the hydrogen permeability during these long term tests were found to be reduced of about 50 and 30% at 673 and 723K, respectively. The reduction in the hydrogen permeability could be correlated to the change in the composition of the coating as well as at the interface between Pd coating and Ni-based amorphous membrane.
