ABSTRACT:
The invention relates to an improved synthesis of fullerene (C.sub.60) films, whereby improved purity and adhesion to a substrate are achieved. The invention is not limited to C.sub.60 molecules and other fullerenes and fullerene based materials, including for example, metallofullerenes, fluorinated fullerenes, and codeposition of fullerene and other solid lubricants. The invention also relates to the use of these fullerene materials in oils, greases, polymers and other materials, both organic and inorganic, for improving lubrication and wear life. The invention further relates to a process for the ion bombardment of fullerene materials, including but not limited to, C.sub.60 fullerene materials to improve their tribological properties.
