摘要
用Devanathan双电解池氢渗透技术测量了20—80℃工业纯铁中氢的扩散系数,D=10.7×10^(-4)exp(-Q/RT),其中扩散激活能Q=7710±150J/mol.本文还讨论了运用电化学法测量氢的扩散系数、制备薄片渗透试样应注意的几个问题.
Hydrogen diffusion coefficient in well-annealed Armco-Fe was measured by an electrochemical hydrogen permeation technique at temperature between 20℃ and 80℃. The analyse of the data susgested diffusion coefficient D = 10.7×10-4 exp(-Q/RT), where Q, the diffusion activity energy, was found to be 7710±150 J/mol. The paper also discussed how to pay attention to problems preparing permeation thin membranes.
