Specific dissipated friction power distributions of machined carburized martensitic steel surfaces during running-in

This contribution shows the SDFP and relates it to the incipient topographies as well as their alterations during run-in. Considering the SDFP being distributed over the sliding domain the affected area (≈real contact area) can be evaluated as well. Now the SDFP can be related to the affected area and the marked differences of the running-in behavior even under ultra-mild sliding wear conditions become visible.
