Lubricating greases containing solid lubricant blends
A solid lubricant blend for enhancing lubricity of lubricating greases. The blend comprises a first stage solid lubricant selected from the group consisting of molybdenum disulfide, graphite, polytetrafluorethylene and mixtures thereof, a second stage solid lubricant of boron nitride, a third stage solid lubricant of an inorganic fluoride characterized by being capable of forming a bonded substantially homogeneous film on a substrate at the elevated temperatures and pressures, and graphene. The solid lubricant blend is mixed with a lubricating grease to attain the lubricating grease compositions of the invention.
CRYOGENIC MACHINING PROCESS USING NANOFLUID
A machining process includes providing a cutting tool having a rake face and a flank face; bringing the cutting tool into contact with a metal alloy work piece to form a chip by penetrating the cutting tool into the workpiece; and introducing a nanofluid into a vicinity of the penetration to remove heat and, in some instances, customize the finished surface. The nanofluid includes a mixture of a cryo-liquid and nanoparticles having a maximum size of approximately 0.1 nanometers to approximately 100 nanometers.
