    Abstract: A lubricant composition is disclosed that includes (a) a machining oil and (b) an exfoliated graphite nanoparticle (EGN) material stably dispersed in the machining oil. The lubricant composition is a stable suspension and is suitable for use as a liquid lubricant in a Minimum Quantity Lubrication (MQL) process. In the MQL process, the lubricant composition is applied/transferred to a worksite in the form of a mist. The presence of the EGN material in the lubricant composition provides high-temperature stability and lubricity under MQL conditions. A very small amount is transferred especially at high cutting speeds where the mist of the machining oil evaporates, but the EGN material remains on the surface to provide lubricity. Any operation involving machining can benefit from this lubricant composition. The method provides important benefits of reducing chipping on cutting tools and providing the additional lubricity especially when the cutting become very hot and thus extending tool life.

    Abstract: The present invention concerns a high-temperature lubricant for the hot shaping of high-grade and carbon steels, which has a content of graphite, organic blowing agent and inorganic separation agent, and the use thereof. In order to provide a high-temperature lubricant which can be used for a wide range of steel qualities for different wall thicknesses to be rolled and stretching effects and which is moreover stable in respect of temperature, provides constant rolling results upon a change in the wall thickness and/or the quality of steel and does not lead to unwanted cementation of the rolled material, the high-temperature lubricant according to the invention contains at least the following constituents in percent by weight with respect to the solids content: (a) 40 to 90% by weight graphite, (b) 2 to 50% by weight organic blowing agent, and (c) 5 to 50% by weight inorganic separation agent, wherein the organic blowing agent (b) is selected from the group consisting of melamine, melam, melem, melon, phosphate salts and polyphosphate salts of the aforesaid compounds with phosphate chain lengths in the region of n=1 to 1000, reaction products and adducts of the aforesaid compounds with cyanuric acid or isocyanuric acid, and mixtures of the aforesaid, and the inorganic separation agent (c) is a sheet silicate or a mixture of sheet silicates.
