Abstract (EN):
This work aims at contributing with experimental results to the evaluation of the wear and the rolling contact fatigue resistance of the wheel-rail contact materials, using a twin-disc machine to simulate the most important dynamic conditions of a real contact. Dry and lubricated tests were performed in order to obtain an extended characterization of the contact fatigue behavior of these two materials. The contact surface integrity was analyzed during these tests.
