Use of the Devanathan–Stachurski cell to measure hydrogen permeation in aluminum alloys

By Free, Michael L
Published in Corrosion Science 2002

Abstract

The Devanathan–Stachurski (DS) cell has been successfully used to determine hydrogen permeation behavior in a wide variety of metals, but the DS cell has been much less successful with aluminum alloys. The DS literature is critically reviewed for aluminum alloys. An improved DS method is described and demonstrated for use with aluminum alloys (and probably Mg-based alloys). Experimental results are reported for the hydrogen diffusion coefficient, solubility, and trapping in the AA5083 aluminum alloy. The diffusion coefficient is reported for AA6061.
