Abstract：The materials used in the hydrogen diffusion calculation experiments is rolled sheet of 40Cr and 4Cr13. CS Electrochemical Workstation is a type of laboratory apparatus which is applicable for diffusing hydrogen atoms， based on the theory of electrochemical methods to let the hydrogen atoms diffuse into the sheet. The preliminary of experiments proceeded with polishing specimens surface， nickel preplating treatment and electroless nickel plating on the rolled sheet， then the diffusion coefficients of hydrogen atoms were tested out and calculated， finally the diffusion coefficients of hydrogen atoms in the rolled sheet of 40Cr were obtained. This experiments can be suit for measuring the hydrogen atoms diffusion coefficient in various metal materials. It plays an important role to quantitativelycalculate the content of the hydrogen in the steel materials. By the comparison of composition and diffusion coefficient of two kinds of material， the effect of metal alloy element content on the hydrogen diffusion in the metal needs further study.
