The fretting corrosion behaviors of Inconel 690 in cathodic condition (CC) and anodic condition (AC) in water environment were investigated. The results indicated that fretting wear behavior, wear mechanism and the microstructure evolution mechanisms in the subsurface strongly depended on polarization condition. There was a thin wear debris layer (WDL) and a thick tribologically transformed structure (TTS) without oxidation in CC; while a thick oxidized WDL and a thin complex TTS consisting of nanocrystalline Ni-rich and Cr-rich oxide zones was observed in AC. The micro-cracks formed at the interface of WDL/TTS in CC, while they formed at the interfaces of Ni-rich/Cr-rich oxide zones and TTS/GDL in AC.
