An overview of methods to suppress hydrogen outgassing rate from austenitic stainless steel with reference to UHV and EXV

Temperature dependence of hydrogen depth distribution in the near-surface region of stainless steel

“…The rate-determining step for the release is considered to be desorption from the surface [15,16]. Up to 400 K, as seen in Fig.…”

Planar High Temperature Heat Pipes for SOFC/SOEC Stack Applications

“…It is believed that this is caused by a small increase of the inactive zone of the heat pipe due to a small outgassing rate of the casing material even over several hundreds of hours after closing [31]. An improved outgassing and baking-out procedure before filling should help to reduce this problem.…”

Use of the finite-element method for a dielectric-constant gas-thermometry experiment

“…The outgassing of hydrogen from stainless-steel may be an essential problem in view of the necessary long measuring time periods. The effect can be reduced by gold layers lowering the hydrogen permeability by more than one order of magnitude [7]. Consequently, all stainlesssteel parts in contact with the measuring gas have been coated with a gold layer of approximately 2 m thickness.…”
