Title (EN) LUBRICANT COMPOSITION
(FR) COMPOSITION DE LUBRIFIANT
Abstract:
(EN) A lubricant composition comprises at least 0.1 % by weight of substantially spherical particles of a hard, abrasion-resistant and fracture-resistant, thermally stable and chemically inert material, and up to 99.9 % by weight of a supporting vehicle. The particles are preferably of silica-alumina ceramic material, and preferably have an average diameter of less than 250 μm. Lubricants are suitable for most applications, but are especially useful for conditions of high temperature and pressure.
(FR) Une composition de lubrifiant comprend au moins 0,1 % en poids de particules pratiquement sphériques d'un matériau dur, résistant à l'abrasion et à la cassure, thermiquement stable et chimiquement inerte, et jusqu'à 99,9 % en poids d'un véhicule porteur. Les particules sont de préférence composées d'un matériau céramique d'alumine-silice, et ont de préférence un diamètre de moins de 250 $g(m)m. Ces lubrifiants conviennent à la plupart des utilisations, mais sont particulièrement utiles dans des conditions de température et de pression élevées.
