Abstract

Wear damage of Alloy 690TT in partial and gross slip fretting regimes at 320 °C was investigated. The obtained fretting regimes were controlled by modifying the displacement amplitude. In partial slip regime, adhesive wear and fatigue crack were the main wear mechanisms. The nanostructured tribological transformed structure (TTS) formed due to incomplete dynamic recrystallization (DRX) with existence of the carbide in TTS. In gross slip regime, oxidation and delamination dominated the fretting wear behavior. The formation of glaze layer resulted in the reduction of wear volume at 320 °C. The TTS with smaller grain size formed due to complete DRX. The oxide type of third body layer consisted of NiCr2O4, NiFe2O4 and Fe2O3, irrespective of slip regime.
