Claims
- 1. A non-reactive halocarbon oil composition suitable for use as a hydraulic fluid and as a lubricant, the composition including a dispersion in the oil of solid lubricant particles having inherent defoaming characteristics, the particles being in the micron size range, and a fluorochemical surfactant possessing foam-generating characteristics in an amount insufficient to generate foam but sufficient to stabilize the dispersion and enhance the lubricity of the oil, said surfactant is a nonionic surfactant belonging to the chemical class of fluorinated alkyl esters.
- 2. A composition as set forth in claim 1, wherein said particles are PTFE.
- 3. A composition as set forth in claim 1, wherein said particles are graphite.
- 4. A composition as set forth in claim 1, wherein the average particle size is no greater than about 5 microns.
- 5. A composition as set forth in claim 1, wherein said particles are angular in shape.
- 6. A composition as set forth in claim 1, wherein said particles by weight are about one part to 1,000 parts of oil.
