Abstract
The present disclosure describes compositions and a method for forming such compositions. More specifically, inorganic microparticles and surface modified silica nanoparticles are mixed to form a composition. The surface modified silica nanoparticles are present in the composition in an amount sufficient to decrease the coefficient of friction relative to a comparable composition that is free of surface modified silica nanoparticles.

A method of forming a lubricant composition comprising:
- mixing a propellant, surface modified silica nanoparticles and inorganic microparticles to form a sprayable dispersion lubricant composition, the inorganic microparticles being substantially spheroidal, wherein the concentration of the surface modified silica nanoparticles is in a range from about 0.001 weight percent to about 5 weight percent based on the total weight of the microparticles and nanoparticles, and wherein the amount of propellant(s) is equal to or greater than 70 weight percent of the total weight of the dispersion.
A method of lubricating a surface of an article comprising:
- providing a sprayable dispersion lubricant composition comprising a mixture of propellant, surface modified silica nanoparticles and inorganic microparticles, the inorganic microparticles being substantially spheroidal, wherein the concentration of the surface modified silica nanoparticles is in a range from about 0.001 weight percent to about 5 weight percent based on the total weight of the microparticles and nanoparticles, and wherein the amount of propellant(s) is equal to or greater than 70 weight percent of the total weight of the dispersion, and
- directing the composition onto the surface of the article to provide a lubricated surface.
A method of forming a lubricant composition comprising:
- mixing a propellant, surface modified silica nanoparticles and inorganic microparticles to form a sprayable dispersion lubricant composition, the inorganic microparticles being substantially spheroidal, wherein the concentration of the surface modified silica nanoparticles, absent the propellant(s), is in a range from about 0.001 weight percent to about 5 weight percent based on the total weight of the lubricant composition, and wherein the amount of propellant(s) is equal to or greater than 70 weight percent of the total weight of the dispersion.
