摘要：

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.
