| Abstract: | The characteristics of debris arising from repetitive compound (sliding) impact are presented. The debris was collected from a variety of tests. Microscopy and X-ray diffraction analysis establish (1) that debris may arise from specimen and counterface, (2) that metallic particles consist of very small and/or distorted primary crystals, (3) that oxide formation occurs and (4) that phase transformations of metallic constituents may occur. Further, particular debris characteristics are shown to be dependent on the nominal contact stress and the relative sliding velocity. |
