HYDROGEN UPTAKE MONITORED BY RESISTANCE CHANGE IN AMORPHOUS ZR33NI67 ALLOY

For determination of the hydrogen content in metallic samples the grav imetric method is generally used, but the large change of the electric al resistivity observed on H-absorption can also be used. The latter m ethod is very effective if the time dependence of the process is impor tant. The resistivity change of the sample can easily be used for moni toring the H-absorption in a gas atmosphere and with some caution for the determination of the H content in galvanic doping as well. Results are presented for the Zr33N67 amorphous alloy with both methods of H charging. Copyright (C) 1996 International Association for Hydrogen En ergy.
