In the context of this work, testing methods of model scale size have been developed, which are based on the ring-on-disc system. These methods enable the visualization of the events in the sliding materials during operation and subsequent breakdown with high time resolution. Therefore, it is possible to visualize and analyze the events taking place at the time of failure. The new test method was benchmarked using the materials AlSn20Cu, CuPb22Sn2 and SnSb7.5Cu3.5. The resulting data enabled the generation of models that characterize the events of the different tribo-materials. Therefore, the proposed method supports the trial-and-error approach of material optimization.
