Abstract

En Bammensetning omfattende: (A) minst et basisk alkali- eller alkalisk Jord- metallsalt alkalisk Jordmetallsalt av en sur organisk forbindelse; (B) minst en metalldeaktlvator forskjellig fra dlmerkaptotladlazol eller derivater derav; og (C) minst en hydrokarbylfosfitt, hvori forholdet mellom ekvivalenter av (A) basert på total- basetall og ekvivalenter av (C) basert på fosforatomer er minst et, forutsatt at sammensetningen er fri for sinkdltio- fosfat og forutsatt at når (A) er et overbaset magneslumsallsylat Inneholder sammensetningen (D) opp til omtrent 0,40 vekt-* av et svovel-, fosfor- eller svovel- og fosfor- inneholdende slitasjehemmende middel. Disse sammenset- ningene er nyttige som tllsetningsstoffer for smøremld- ler og funksjonelle fluider, spesielt hydrauliske fluider, giroljer, fett og lignende, er beskrevet. Smøreoljemldler og fluider som har denne bestemte kombinasjonen av komponenter har forbedret termisk stabilitet og Inneholder Ikke slnkdltlofosfat. Disse smøremidlene og fluidene er heller ikke korroderende for de hydrauliske systemkomponentene.A Tree Composition comprising: (A) at least one basic alkali or alkaline earth metal salt alkaline earth metal salt of an acidic organic compound; (B) at least one metal deactivator other than dimercaptotladlazole or derivatives thereof; and (C) at least one hydrocarbyl phosphite, wherein the ratio of equivalents of (A) based on total base number to equivalents of (C) based on phosphorus atoms is at least one, provided that the composition is free of zinc dithiophosphate and provided that (A) is an overbased magnesium slum salate Contains the composition (D) up to about 0.40% by weight of a sulfur, phosphorus or sulfur and phosphorus-containing anti-wear agent. These compositions are useful as additives for lubricants and functional fluids, especially hydraulic fluids, gear oils, greases and the like. Lubricant oil fluids and fluids having this particular combination of components have improved thermal stability and do not contain sludge lyophosphate. These lubricants and fluids are also not corrosive to the hydraulic system components.
