Abstract

The electrochemical hydrogen_permeation technique was used to study hydrogen permeation through zinc electrodeposit with bilayer specimens of Fe substrate/zinc electrodeposit.The effect of coating thickness on hydrogen diffusion coefficient and hydrogen steady-state flux was studied. The results showed that hydrogen diffusion coefficient was approximately in the range of 10-11 cm2s-1 rank and zinc coating could retard hydrogen permeation. Accordingly, hydrogen steady_state flux and effective diffusion coefficient declined while the coating thickness increased.
