An electrochemical double-cell technique was used to study the binding and diffusion behaviour of hydrogen in the metallic glass, Ni60Zr40. The diffusion constants varied from 10-14 to 10-12m2/s; depending upon the hydrogen concentration. The variation of the chemical potential of hydrogen with concentration in this system was consistent with a broad distribution of binding energies.
