Evaluation of hydrogen-trap binding enthalpy II

On the Boundary Conditions of Electrochemical Hydrogen Permeation Through Iron

“…Hydrogen traps have great influences on hydrogen permeation and, therefore, have attracted many researchers. [27][28][29][30][31] In addition to Fick's second law, one needs another governing equation to describe the trap behavior. The two equations couple to one another and, in general, are nonlinear.…”

“…Iino has tabulated the binding energies for various traps in iron 30 and analyzed the effects of traps on the permeation behavior. 31 The present work focuses on the boundary conditions, i.e., on the surface effects. Therefore, we do not discuss hydrogen traps hereafter in this paper.…”

“…Interested readers may refer to references. [27][28][29][30][31] In recent publications, Zhang and Zheng have proposed a new model on the basis of flux continuity, 19,20 and thus we call it the flux continuity (FC) model. If the diffusivity is evaluated from the FC model, it is independent of the sample thickness.…”
