Spalling was a major form of contact fatigue failures in nitriding steel.
It is possible that many failure modes have emergence during the structural service period. For example, dead load strength failure, stiffness failure and fatigue failure.
The surface spalling and fatigue failure may occur after a long time of service, during wheel-rail rolling contact.
This will lead to roll failure such as fire crack, surface crack, and fatigue failure.
The fretting fatigue behavior of TC4 alloy was investigated using cylinder-plane configuration. Based on the experimental results, the damage mechanism of fretting fatigue failure was discussed.
The fatigue crack growth curve from initial crack size till fatigue failure is simulated step by step.
We have made certain that the reason of the splined spindle rapture is fatigue failure, its crack initiation lies in the minimal knuckle curvature radius surface region of the spline dedendum bottom.
The results indicated that the fracture mode is the fatigue failure.
But the study on the rolling contact fatigue failure mechanism of super hard material coati-ngs is in grope.
