Abstract:
A composition comprising:(a) a major portion of a lubricant base, selected from the group consisting of petroleum derived lubricants, synthetic hydrocarbons, polyether oils, carboxylic esters, phosphoric acid esters, silicone containing oils, and halogenated hydrocarbons and halocarbons; and (b) a minor portion of a first lubricant additive which is an organic compound which is grafted with one or more fluorinated olefins and which, when combined with a lubricant base forms a fluorine-containing lubricant, the amount of fluorine in the lubricant composition being 200 parts per million to 10 per cent by weight; and provided that: said additive contains at least 5 percent by weight of fluorine; and said organic compound contains at least one functional group which can be adsorbed on a metal surface and wherein said functional group is selected from the group consisting of carboxylic esters, carboxylic acids, carboxylic amides, imides, amines, phosphoric acid derivatives, phosphonic acid derivatives, dithiophosphate esters, ethers, hydroxyls, carbonates, thio derivatives thereof, and heterocyclic groups: and wherein said fluorine-containing lubricant contains 200 parts per million to 10 percent by weight of fluorine.
