The Torsional Fretting Wear Behavior of Titanium Alloy

Torsional fretting behavior of TC4 titanium alloy has been investigated at different parameters to explore the wear resistance and mechanisms alloy. The loops, dissipated friction energy torque under normal load (100N 200N), angular displacement (±0.5° ±2°) frequency (10Hz 15Hz) were studied reveal mechanical during fretting. Results showed that made difference in while was most important factor energy. And ran gross slip regime above parameters. Surface morphology scars characterized by optical microscopy scanning electron microscopy. shape hourglass, appearing narrow shallow middle, wide deep on both sides. section profiles “V”. Besides, depth volume increased larger displacement. SEM images depicted adhesive wear, delamination fatigue occurred
