英文摘要
Oxide species of which solubility of hydrogen is extremely low has been investigated based on literature survey. It has been considered that Cr2O3 shows excellent performance from the suppression of hydrogen permeation point of view.Hydrogen permeability of the oxide layer which formed on type 430 stainless steel with different condition of surface finish and oxidation treatment has been evaluated by electrochemical hydrogen permeation technique. Even a nanometer-scaled Cr rich oxide decrease the hydrogen permission current significantly. Different hydrogen permission current behaviors have been found for different type of surface finish and it may be due to the difference in protectiveness of oxide layer.
