Abstract : The transient current of hydrogen removal from iron following steady state permeation is analyzed theoretically for two limiting conditions at the i9nput side. For the fastest possible removal (C = 0 at X = 0 and at X = L), the amount extracted at the potentiostated side (X = L) is one third of the total present at steady state permeation described by Csub(X) - Csub(1 - X/L). Comparison of the integrated total flux and the amount given by the integral of Csub(X) indicates possible concentration dependence of hydrogen diffusivity in iron. (Author)
