<p>A lubricity additive composition includes a lubricating medium and, dispersed therein, cerium dioxide nanoparticles having a mean hydrodynamic diameter of about 1 nm to about 15 nm. In a method for reducing friction between, or scarring, abrasion, or pitting of metal surfaces in relative motion with one another, at least one of the metal surfaces has been contacted with a lubricity additive composition that includes a lubricating medium and, dispersed therein, cerium dioxide nanoparticles whose mean hydrodynamic diameter is about 1 nm to about 15 nm.</p> |
