Abstract

In this paper we present an analysis which allows for an experimental determination of an upper bound to the characteristic length scale in a gaseous hydrogen embrittlement system. Our approach is based upon an ac analysis of the coupled adsorption diffusion equations for the hydrogen metal system. We show how the frequency of the driving pressure affects the depth below the surface at which surface and bulk processes effectively decouple from one another. This decoupling distance serves as a useful probe for the location of the so-called hydrogen embrittlement process zone.
