Abstract

Fretting corrosion of hydrided Zr-alloy under gross slip regime in high temperature high pressure water were investigated. The results indicated that hydrogen charging decreased wear volume significantly. At low hydrogen content, tetragonal ZrO₂ was formed at the oxide/tribologically transformed structure (TTS) interface, which induced cracks and delamination. From worn surface to matrix there were third body layer (TBL), TTS and deformation layer. At high hydrogen content, an oxide layer consisting mainly of monoclinic ZrO₂ was formed, from worn surface to matrix there were TBL, oxide layer, TTS and deformation layer, and the main damage mechanisms were oxidation and adhesive wear.

水合锆合金在高温高压水环境中粗滑状态下的摩擦腐蚀行为和微观结构演变

研究了高温高压水中毛滑移状态下水合 Zr-合金的摩擦腐蚀。结果表明，充氢可显著减少磨损量。在氢含量较低时，氧化物/三态转化结构（TTS）界面上形成了四方 ZrO2，从而诱发了裂纹和分层。从磨损表面到基体有第三体层（TBL）、TTS 和变形层。氢含量高时，形成了主要由单斜ZrO2组成的氧化层，从磨损表面到基体有TBL、氧化层、TTS和变形层，主要的破坏机制是氧化和粘着磨损。
