Definitions

  • the present invention relates to lubricant additives and formulations, and more particularly to lubricant additives and formulations for use in connection with rotorcraft transmission and gearbox systems, and other rotary platforms.
  • Metal parts in close tolerances and contacts are a design feature of many electromechanical and mechanical devices.
  • Lubricants maintain viscosity and protect components more effectively under the high shear stresses that these systems place on metal parts.
  • the benefits of a well-lubricated system include an increase in the effective service life of the constituent parts of the system and the system as a whole, as well as enhanced fuel efficiency, which can lead to significant cost savings. In a typical engine set-up, 10-15% of the energy is lost due to friction.
  • Ionic liquids have been known to enhance the lubricity of a system/material, for example as disclosed in U.S. Pat. Nos. 8,318,644 and 7,754,664, and the article "Ionic Liquids in Tribology" (Minami, Ichirio, Molecules 14, no. 6 (2009): 2286-2305), each of which is incorporated by reference herein in its entirety. Due to the inherent polarity of ionic liquids, they adsorb strongly on the metallic tribocontact surfaces leading to a robust tribofilm when compared to conventional lubricants. However ionic liquids have an intrinsically high cost. Also, the use of some ionic liquids having halogens can also result in undesirable corrosion of metal surfaces having specific compositions.
  • Metal nanoparticles have also emerged as an approach to advanced development for enhanced lubrication and heat transfer capability.
  • incorporating metal nanoparticles into the tribofilm can enhance rolling friction between the contact surfaces, thereby reducing wear.

  • the organic nanoparticle has a median particle size less than about 200 nm.

  • the ionic liquid of the additive composition may be any of a variety of ionic liquids, or combinations thereof.
  • the addition of an ionic liquid to the base lubricant appears to facilitate rapid formation of a protective tribocoating on metal surfaces of the system incorporating the lubricant.
  • the ionic liquid is a non-corrosive ionic liquid, such as a halogen-free ionic liquid, to reduce wear on system parts.
  • the halogen- free nature of the ionic liquid reduces sensitivity for hydrolysis, which in turn reduces the incidence of corrosion.
  • Ionic liquids are known in the art, and selection of a suitable ionic liquid may be based on factors such as lubricity and the ability to protect against corrosion.

  • gear steel with the ionic liquid may have a coefficient of friction less than that of the base lubricant.
