COMPOSITE MATERIAL COMPRISING POROUS MATRIX MADE OF METAL AND HOLLOW FULLERENE-LIKE NANOPARTICLES, METHOD OF REDUCING FRICTION COEFFICIENT AND WEAR RATE AND OF INCREASING LOAD BEARING CAPACITY, AND METHOD OF PREPARING COMPOSITE MATERIAL

摘要

The present invention provides a new composite material comprising a porous matrix made of metal, metal alloy or semiconducting material and hollow fullerene-like nanoparticles of a metal chalcogenide compound or mixture of such compounds. The composite material is characterized by having a porosity between about 10% and about 40%. The amount of the hallow nanoparticles in the composite material is 1-20 wt. %.
