Abstract

A bearing or other support member containing intercalated graphite exhibits many of the properties of a metal (ie: conductivity, luster, ductility) while enhancing the lubricating properties of pure graphite. The bearings are made by pressing an intercalated graphite powder either alone or mixed with metal powders, organic polymers or ceramic powders into the desired shape. This results in a bearing that has low friction properties, improved load bearing characteristics, higher operating temperatures and a reduced cost of manufacture.
