Appeal No. 94-3447
Application 07/864,725
maintaining a substrate within a bed of particles capable of
being fluidized, said particles having substantially uniform
dimensions and said substrate characterized as having different
dimensions than the particles;
fluidizing the bed of particles;
depositing a coating of diamond upon the substrate by
chemical vapor deposition of a carbon-containing precursor gas
mixture, said precursor gas mixture introduced into the fluidized
bed of particles in quantities, at pressures and at temperatures,
under conditions resulting in excitation mechanisms sufficient to
form said diamond coating.
2. The process of Claim 1 wherein the substrate is further
characterized as comprised of a different material than the bed
particles.
3. The process of Claim 1 wherein the substrate is further
characterized as comprised of the same material as the bed
particles.
11. A process for coating a substrate with diamond
comprising:
maintaining a substrate within a bed of particles capable of
being fluidized, said particles having substantially uniform
dimensions and said substrate characterized as comprised of a
different material than the particles;
fluidizing the bed of particles;
depositing a coating of diamond upon the substrate by
chemical vapor deposition of a carbon-containing precursor gas
mixture, said precursor gas mixture introduced into the fluidized
bed of particles in quantities, at pressures and at temperatures,
under conditions resulting in excitation mechanisms sufficient to
form said diamond coating.
