Zusammenfassung:	The present invention is directed to a wear and friction article, comprising on at least one of the surfaces thereof a polymeric material comprising: 20 to 100% by weight of at least one polyetherketoneketone (PEKK); 0 to 80% by weight of one or more fillers; and 0 to 20% by weight of one or more additives. It further concerns the use of such a polymeric material for reducing wear and/or friction at elevated temperature. La présente invention concerne un article soumis à usure et frottement, comprenant sur au moins l'une de ses surfaces un matériau polymère comprenant : de 20 à 100 % en poids d'au moins une polyéthercétonecétone (PEKK) ; de 0 à 80 % en poids d'une ou de plusieurs charges ; et de 0 à 20 % en poids d'un ou de plusieurs additifs. L'utilisation dudit matériau polymère pour réduire l'usure et/ou le frottement à température élevée est en outre décrite.
