Patent ID: 8216986

Claim:
The lubricant additive produced by the process comprising: mixing a metal fluoride with a pentavalent, mono- or di-thiophosphate, the metal fluoride participating as a reactant, wherein the metal fluoride is selected from the group consisting of: aluminum trifluoride, zirconium tetrafluoride, titanium trifluoride, titanium tetrafluoride, ferric fluoride, chromium difluoride, chromium trifluoride, nickel difluoride, stannous difluoride, stannous tetrafluoride, and combinations thereof; and reacting the metal fluoride and the pentavalent, mono- or di-thiophosphate to produce a reaction mixture comprising the lubricant additive, wherein said reacting comprises heating to a temperature from about 60° C. to about 125° C., the reaction producing, in the lubricant additive, at least one compound that comprises at least one phosphorus-fluorine bond.
