摘要	By using a specially designed device and gas permeation method, the hydrogen diffusion coefficients for the tube-shape samples of Cr18Ni10Ti austenite steel were measured. The testing temperature covers the range of 360-600 degreesC. The curves of hydrogen permeation flux and the relation of hydrogen diffusion coefficients and specific time were simulated by finite difference method (FDM). According to the simulated curves the experiment data related to the hydrogen. diffusion coefficients can be treated. The hydrogen diffusion coefficients for aluminum film inner coated tubes at room temperature is 5.789x 10(-20) m(2) /s, its activation energy of hydrogen diffusion is 8.144x 10(-20) J/mol, which are 5-6 orders lower and 1 times higher than those of uncoated tubes respectively.
