Testing for the Relative Susceptibility of Materials to Internal Hydrogen Embrittlement by Electrochemical Techniques

Abstract

An electrochemical test method is proposed for determination of the susceptibility of materials to internal hydrogen embrittlement (IHE). The method is based on the assumption that the relative susceptibility of a material depends both on the specific aqueous environment to which the material is exposed and to the dissimilar materials to which it is coupled. Potentiosatic techniques are employed to impress potential on sustained loaded notched round- bar specimens. The result is a plot of impressed potential versus time-to- failure; superpositioning of the resultant curves provides a basis for rating the relative susceptibility of various materials to IHE.
