Appeal No. 2001-0214
Application No. 08/826,283
1. A composition for lubricating contacting surfaces
on components in relative motion to each other comprising:
a) a lubricant, and
b) a colloidal suspension having elemental nano-phase
metallic core particles selected from the group consisting
essentially of bismuth, tin, zinc, copper, and silver and a
surfacant adhering to and surrounding the metal core, the
lubricant composition being characterized in that it coats
the said contacting surfaces to which it is applied and fill
in surface asperities in those surfaces to extend the life
of the contact surfaces.
9. A metallic nano-phase colloidal suspension for
lubricating contacting surfaces on components in relative
motion to each other comprising
a) an elemental metal core selected form [sic, from]
the group consisting essentially of bismuth, tin, zinc,
copper, and silver, and
b) a surfacant, the colloidal suspension having a
metal content by weight of about 6-30% and a surfacant by
weight of about 70-94% and being characterized in that it
coats the said contacting surfaces to which it is applied
and fills in surface asperities in those surfaces to extend
the life of the contacting surfaces.
12. A rolling element bearing lubricant composition
comprising
a) a lubricant selected from the group consisting
essentially of oils, greases and polyalphaolefins,
b) elemental nano-phase metallic particles selected
from the group consisting essentially of bismuth, tin, zinc,
copper, and silver,
