摘　　要：根据费克第二定律提出了热浸镀铝钢双层体系氢扩散系数解法．根据上述结果，用电化学方法测定了氢的扩散行为；测定了渗铝层不同温度下氢的扩散系数和渗铝层氢扩散激活能．A way of solving hydrogen diffusion equation in the double layer system of hot dip aluminum steel is put forward on the basis of the second Fick diffusion law. Hydrogen diffusion behavior in the system is studied with electrochemical method according to the results mentioned above. The diffusion coefficient and activation energy of hydrogen in the double layer system at different temperature is also measured.
