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。
Hydrogen diffusion calculation of metal sheet materials selected for the test 40Cr and 4Cr13 rolled sheet, the use of electrochemical hydrogen diffusion test. Through the surface treatment of the sheet and the pretreatment of nickel and nickel plating, the determination of the hydrogen diffusion coefficient is finally carried out, and the hydrogen diffusion coefficient is calculated according to the data parameters obtained by the hydrogen diffusion test. Finally, hydrogen Diffusion coefficient. Hydrogen diffusion calculation test is suitable for the determination of hydrogen diffusion coefficient of various metal materials. It provides the basic parameters and calculation basis for detecting the hydrogen accumulation during the use of steel, and plays a crucial role in the quantitative calculation of hydrogen in materials. By comparing the composition and diffusion coefficient of the two materials, the effect of the mass fraction of alloying elements in the metal on the diffusion of hydrogen in the metal is further studied.
