Title
(EN) WATER LUBRICANT COMPOSITION AND WATER LUBRICATING SYSTEM
(FR) COMPOSITION AQUEUSE LUBRIFIANTE ET SYSTÈME AQUEUX DE LUBRIFICATION
(JA) 水潤滑剤組成物および水潤滑システム
Abstract
(EN)
This water lubricant composition (10) includes water (11) as a base lubricant and ND particles (12) which are hydrogen-reduced nanodiamond particles. The content ratio of water (11) in the water lubricant composition (10) is at least 90% by mass, for example. The content ratio of ND particles (12) in the water lubricant composition (10) is no more than 0.1% by mass, for example. Such a water lubricant composition (10) is suitable for realizing low friction in water lubrication. {In this water lubricating system, a water lubricant composition (10) such as described above is used to lubricate an SiC member and/or an SiO2 member.
(FR)
La présente invention concerne une composition aqueuse lubrifiante (10) comprenant de l’eau (11) comme lubrifiant de base et des particules ND (12) qui sont des nanoparticules de diamant réduites à l’hydrogène. Le rapport de teneur en eau (11) dans la composition aqueuse lubrifiante (10) est d’au moins 90 % en masse, par exemple. Le rapport de teneur en particules ND (12) dans la composition aqueuse lubrifiante (10) est inférieur ou égal à 0,1 % en masse, par exemple. Une telle composition aqueuse lubrifiante (10) convient à l'obtention d’un frottement faible dans la lubrification aqueuse. {Dans ledit système aqueux de lubrification, une composition aqueuse lubrifiante (10) telle que décrite ci-dessus est utilisée pour lubrifier un élément SiC et/ou un élément de SiO2.
