WebDec 1, 2011 · The effect of absorbed hydrogen and surface oxide layer on creep properties was investigated for the Zircaloy-4 fuel cladding tube. The hydrogen was charged differently by using a vacuum chamber with a fixed hydrogen gas flow, and also by corrosion test in a steam atmosphere. WebJun 19, 2024 · The effect was attributed to hydrogen release into the coating from the reaction between yttrium and water vapor and the subsequent formation of hydrogen gas at the internal coating defects (pores). Few experiments on freestanding bond coats have compared the influence of atmospheres containing H 2 O and/or H 2 on creep properties.
