Abstract:
Additive packages including multifunctional additive molecules are disclosed, including, for example, organic medium intercalated with lubricant nanoparticles. The additive package may be greaseless or may he added to materials such as base oils or greases, greaseless materials, or anti-corrosives, for example. The additive package added to materials may form a coating or lubricant that may be added to a surface of an object.
Abstract:
A composition that includes solid lubricant nanoparticles and an organic medium is disclosed. Also disclosed are nanoparticles that include layered materials. A method of producing a nanoparticle by milling layered materials is provided. Also disclosed is a method of making a lubricant, the method including milling layered materials to form nanoparticles and incorporating the nanoparticles into a base to form a lubricant.
Abstract:
The engine oil additive contains multiple 300 to 500 nm-long polygonal plate-shaped silver crystal particles. The engine oil contains a base oil and the engine oil additive. The method of adding the additive to an engine oil includes adding multiple 300 to 500-nm-long polygonal plate-shaped silver crystal particles as an additive to the engine oil.

Abstract:
A lubricating fluid composition for dynamic pressure bearings which supports the shaft of the bearing by dynamic pressure, wherein the lubricating fluid composition comprises fine magnetic particles dispersed in a base oil solvent which comprises a hydrogenated poly-.alpha.-olefin (PAO) and a polyol ester.
Abstract:
A process for preparing improved solid lubricants, by modifying the surface characteristics of the solid lubricants using reactive chemical compounds, is disclosed.Prior art measures anticipate combinations of modifiers and solid lubricants as lubricating mixtures but do not disclose bonding modifiers with solid lubricants.Examples of the improved modified solid lubricants are molybdenum disulfide chemically bonded to polystyrene, polymethylmethacrylate or polydimethylsiloxane.
Abstract:
An extreme pressure lubricant composition comprising a lubricating oil containing O-ethyl-S-n-butylthiosulfenyl xanthate, O-ethyl-S-tert-butyl-thiosulfenyl xanthate, t-butyl-t-butylthiosulfinate, or a polymeric polysulfide of a mercaptoethyl cyclohexane thiol.
Abstract:
A process for preparing clear bright oleaginous aluminum dispersions comprising admixing an oil soluble dispersing agent, an oleaginous carrier and a volatile solvent with a dispersible alumina, heating and recovering a clear bright oleaginous aluminum dispersion.
Abstract:
COMPACTION OF A POWDERED MIXTURE OF GROUP V-B, VI-B OR RARE EARTH CHALCOGENIDES AND A REFRACTORY METAL UNDER SUFFICIENT HEAT AND PRESSURE TO SINTER THE POWDER MIXTURE AND TO REACT AT LEAST SOME OF THE REFRACTORY METAL WITH CARBON TO FORM A METAL MATRIX SOLID LUBRICANT COMPOSITE CONTAINING A REFRACTORY METAL CARBIDE. GRAPHITE DIES MAY BE USED TO PROVIDE CARBIDE FORMATION.
