Inspection of Friction and Wear Properties of Railway Rails
Transcript of Inspection of Friction and Wear Properties of Railway Rails
O. Nuri ÇELİK Inspection of Friction and Wear
Properties of Railway Rails Rail Wheel Contact Materials Otectoid non-alloyed steel Method Microstructural tests Wear Behaviour Average Friction Coefficient
Wet: 0.15 Microstructural
Results 1.344.566.000TL is spent
on railways Effect of wear can be understood
by charecterization of rail. Train loads
influence wear behaviour. Wear tests 2% Nital etchant was used Speeds
Dry SEM Dry Conditions SEM Wet Conditions EDS
Results Dry Wet Conclusion Oxide formations on surfaces
Oxide Layers on Dry surfaces are denser.
Friction Coefficient results show lubrication effect on dry surfaces.
Thus oxides on dry surfaces are Fe3O4 Oxides formed at Wet conditions are
Small sized These oxides are easier to break as seen at 12cm/s experiments.
Thus cause abrasive effect and increase wear. Using wear resistant material
Reducing bend radius
will reduce wear. You can view this presentation at
