Abstract: The electrochemical hydrogen penetration measurement technique, to which a sinusoidal perturbation method was applied, was modified using a signal containing multiple frequency components. The technique was successfully applied to measurement of the hydrogen diffusion coefficient in a ferric sheet specimen. A series of numerical calculations for the technique, in which the constituent frequencies of the signal were selected from the measurement result, also provided the same diffusion coefficient and verified the validity of the technique. The use of this technique enables rapid determination of the hydrogen diffusion coefficient in a specimen.
