金属板材氢扩散计算试验选用材料为40Cr及4Cr13轧制板材,运用电化学方法进行氢扩散试验。通过对薄板进行表面处理,且进行预镀镍及镀镍的处理,最终进行氢扩散系数的测定试验,并根据氢扩散试验得到的数据参数进行氢扩散系数的计算,最终得到两种钢的氢扩散系数。氢扩散计算试验适用于各种不同金属材料氢扩散系数的测定,为检测钢在使用过程中氢的积累提供基本参数及计算依据,且对于材料中氢的定量计算起到至关重要的作用。通过对两种材料成分及扩散系数的比较,进一步研究金属中合金元素质量分数对氢在金属中扩散的影响作用。

英文摘要：

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 experi- ments 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.
