Title (EN) FUNCTIONAL FLUID COMPOSITIONS CONTAINING EROSION INHIBITORS
(FR) COMPOSITIONS DE FLUIDE FONCTIONNEL CONTENANT DES INHIBITEURS D'ÉROSION
Abstract:
(EN) A functional fluid composition containing a fluid base stock (e.g., a phosphate ester fluid base stock) as a major component, and an erosion inhibitor mixture as a minor component. The erosion inhibitor mixture contains at least a first erosion inhibitor (e.g., a perhalometaliate or perhalometalloidate salt) and a second erosion inhibitor (e.g., an alkali metal salt of perfluoroalkyl sulfonic acid). Erosion inhibition of the functional fluid composition is improved as compared to erosion inhibition achieved using singly the first erosion inhibitor or the second erosion inhibitor, as measured by one or more of ASTM D2624, ASTM D974, ASTM D130 and ASTM D6304. A method for operating and lubricating a hydraulic system by utilizing as a hydraulic fluid, the functional fluid composition. A method for identifying erosion inhibition effectiveness of the functional fluid. The functional fluids are useful as aircraft hydraulic fluids.
(FR) La présente invention concerne une composition de fluide fonctionnel contenant une solution mère de base de fluide (par exemple, une solution mère de base de fluide d’ester de phosphate) en tant que composant majeur, et un mélange d’inhibiteurs d'érosion en tant que composant mineur. Le mélange d’inhibiteurs d’érosion contient au moins un premier inhibiteur d’érosion (par exemple, un perhalogénométallate ou un sel de perhalogénométallate) et un deuxième inhibiteur d’érosion (par exemple, un sel de métal alcalin d’acide perfluoroalkylsulfonique). L’inhibition d’érosion de la composition de fluide fonctionnel est améliorée par rapport à l’inhibition d’érosion obtenue en utilisant uniquement le premier inhibiteur d’érosion ou le deuxième inhibiteur d’érosion, telle que mesurée par l’un ou plusieurs d’ASTM D2624, ASTM D974, ASTM D130 et ASTM D6304. L’invention concerne en outre un procédé de fonctionnement et de lubrification d’un système hydraulique en utilisant en tant que fluide hydraulique, la composition de fluide fonctionnel. L’invention concerne en outre un procédé d’identification de l’efficacité d’inhibition d’érosion du fluide fonctionnel. Les fluides fonctionnels sont utiles en tant que fluides hydrauliques d’aéronef.
