Three types of surface finishes with mean roughness Ra ranging from nano- to micro-scale were investigated. Tribo-sintering of nanopartides, oxidation of counterface steel and compaction of wear debris are identified to be competing factors dominating the formation and function of the tribofilms. Counterface topography played an important role on the competing factors, and thereby influenced significantly the final structure, the load-carrying capability and the lubrication performance of the tribofilms. It was disclosed that a thin tribofilm, which mainly consists of silica nanoparticles and which forms on the counterface with a submicron roughness, benefits best the tribological performance of the composites PB - Butterworth-Heinemann CY - Oxford KW - Surface topography KW - Nanocomposite KW - Tribology KW - Tribofilm PY - 2015 UR - https://opus4.kobv.de/opus4-bam/frontdoor/index/index/docId/34612 AN - OPUS4-34612 SN - 0301-679X VL - 83 SP - 156 EP - 165 AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany
