HYDROGEN DIFFUSION BEHAVIOR OF HOT DIP ALUMINUM STEEL
热浸镀铝钢氢的扩散

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.
