TY - CONF A1 - Burbank, John Theodore A1 - Scholz, Christian A1 - Woydt, Mathias T1 - Reactive boundary layers in metallic rolling contacts T2 - Gordon Research Conf.: Tribology N2 - The running-in phase of mechanical systems is critical from a tribological standpoint, because microcracks, a cause of material failure, can appear during this phase of heightened friction and wear. The ultimate goal of this current work is to transfer the running-in phase into the finishing process through the preconditioning of novel, high toughness steel bearings and compare these to conventionally used steels. This has been achieved both through the generation of tribo-reactive films and cold work hardening of the steel surface substrates. Determination of the presence of reactive tribofilms was achieved via SEM-EDX with Element-Mapping, whereas the effects of cold work hardening on the samples were observed through measurement of localized hardness and residual stresses. Both tribofilm-protected samples and cold work hardened samples were then subjected to long term slip-rolling testing (10,000,000 cycles, approximately 19 days) to determine any changes in friction behaviour or wear performance.
