Measurement of the Permeability of Metals to Hydrogen at Room Temperatures

Abstract

Previous measurements of hydrogen permeation of metals have been limited to high temperatures where permeation rates are relatively high and pressure-sensing devices can be employed to measure the permeating gas. Permeation rates at room temperature can be measured by the use of tritium (the radioactive isotope of hydrogen) and conventional counting equipment. With the equipment and techniques described in this report, it is possible to measure hydrogen permeation rates on the order of 10(exp -17) cm3 (STP)/(sec)(cm2) per mm thickness of metal.
