Abstract
A nanolubricant composition is described where the lubricant composition includes a flowable oil or grease with a multi-component nanoparticle dispersed in the flowable oil or grease. The multi-component nanoparticle includes a first nanoparticle component which effects thermal conductivity at a part interface and a second nanoparticle component which effects shearing at a part interface.
Claims23
A nanolubricant composition comprising;
- a flowable lubricant;
- and
- a multi-component nanoparticle dispersed in the lubricant, the multi-component nanoparticle including a first nanoparticle component which effects thermal conductivity at a part interface and a second nanoparticle component which effects shearing at a part interface, the second nanoparticle component at least partially integrated with the first nanoparticle component and the first nanoparticle component enhancing thermal conductivity of the nanolubricant to a greater extent than the second nanoparticle component.
A nanolubricant composition comprising;
- a viscous lubricant;
- and
- a multi-component nanoparticle, the multi-component nanoparticle including a thermal conductivity modifying nanoparticle component and a friction modifying nanoparticle component at least partially integrated with the thermal conductivity modifying nanoparticle component, the thermal conductivity modifying nanoparticle component is selected from the group consisting of diamond nanoparticles, carbon nanotubes, silver, copper, aluminum nitride, and mixtures thereof and has an average particle size in the range of from about 1 nm to about 25 nm and comprises from about 0.1 to about 5 weight percent of the nanolubricant composition and the friction modifying nanoparticle component is selected from the group consisting of molybdenum disulfide, tungsten disulfide, hexagonal boron nitride, graphite and mixtures thereof, and has an average particle size of from about 10 to 100 nm and comprises from about 0.1 to about 5 weight percent of the nanolubricant composition.
