Abstract
A nanolubricant composition is described where the lubricant composition includes a flowable oil or grease with nanoparticles dispersed in the flowable oil or grease. The nanoparticles are configured to polish a surface of a structure slowly over a period of time. The nanoparticles a hardness of at least about 7 Mohs and a diameter that is less than one half the arithmetic average roughness of the surface or a length that is less than one half of the arithmetic average roughness of the surface.

A nanolubricant composition for polishing a surface having an arithmetic average roughness, the composition comprising:
- a flowable lubricant;
- and
- nanoparticles dispersed in the lubricant and configured to polish the surface, the nanoparticles having a hardness of at least about 7 Mohs and a diameter that is less than one half the arithmetic average roughness or a length that is less than one half of the arithmetic average roughness.
A nanolubricant composition for polishing a surface having an arithmetic average roughness, the composition comprising:
- a flowable lubricant;
- and
- a multi-component nanoparticle dispersed in the lubricant and configured to polish the surface, the multi-component nanoparticle including a first nanoparticle component which effects shearing at the surface and a second nanoparticle which effects polishing of the surface, the second nanoparticle component at least partially integrated with the first nanoparticle component, the second nanoparticle component having a hardness of at least about 7 Mohs (equivalent to 820 kg/mm2 in Knoop scale).
A method of in-situ nanopolishing a contact surface having an arithmetic average roughness, the method comprising the steps of:
- providing a nanolubricant including a flowable lubricant and nanoparticles, the nanoparticles dispersed in the lubricant and configured to polish the surface, the nanoparticles having a hardness of at least about 7 Mohs (equivalent to 820 kg/mm2 in Knoop scale) and a diameter that is less than one half the arithmetic average roughness or a length that is less than one half of the arithmetic average roughness;
- and
- polishing the contact surface using the nanolubricant to increase the ratio of a film thickness of the nanolubricant at the surface to the composite roughness.
