Abstract

In this work, the hydrogen and deuterium transport parameters such as permeability, diffusivity, and solubility in a Pd-25 pct Ag alloy are studied, using a permeation gas phase technique and, additionally, a computer-controlled microbalance system. In the region in which Sieverts' law is valid, the hydrogen solubilities found using both techniques are in very good agreement. From permeation measurements, the surface constants for the adsorption (σk1) and release (σk2) of hydrogen and deuterium in Pd-25 pct Ag alloy are also determined. The measurements cover the temperature range from 323 to 773 K and a pressure range from 1 to 105Pa.
