Abstract

L'invention concerne une composition d'additif de lubrification qui comprend un milieu lubrifiant et, dispersées dedans, des nanoparticules de dioxyde de cérium ayant un diamètre médian d'environ 1 nm à environ 15 nm. Dans un procédé de réduction du frottement, de l'éraflure, de l'abrasion ou de la piqûration de surfaces en métal en mouvement relatif les unes par rapport aux autres, au moins une des surfaces en métal a été mise en contact avec une composition d'additif de lubrification qui comprend un milieu lubrifiant et, dispersées dedans, des nanoparticules de dioxyde de cérium dont le diamètre médian est d'environ 1 nm à environ 15 nm.
