Multi-layer low friction and low wear polymer/polymer composites having compositionally graded interfaces

摘要: A high strength multi-layer polymeric article having a low wear surface includes base polymer layer, and composite capping layer disposed on the layer. The first including transfer film forming polymer, second different from for strengthening this mixed with polymer. provides at least 10 weight % of transition is interposed between portion providing non-constant or concentration. rate <10−7 mm3/Nm. can be PTFE polyaryletherketone (PEEK).
