A double-cell electrochemical technique was used to study H permeation in amorphous alloys. The H diffusivity versus H-content relationships were determined for all of the alloys (table 152). In each alloy, the H diffusivity increased markedly with increasing H concentration. This implied that there existed a broad range of energy states for H incorporation in the amorphous material. Data on crystallized samples revealed substantial differences in the diffusivity behavior of the amorphous and crystalline states.
