ABSTRACT:
Fluidized bed process for coating materials with pyrolytic carbon. A gaseous atmosphere including a carbonaceous substance is flowed upward through a vertical heated enclosure to fluidize a bed of particles therein. An exit conduit extends into the particle bed and a controlled flow of inert gas is fed through the conduit to regulate the exit passage of particles from the bed. Additional particles are added to the bed from above.
