It has generally been observed that in order in expedite the formation of chemical vapor deposited (CVD) diamond coatings, it is desirable to prepare a substrate by ``seeding`` it with diamond powder. We have determined that thick, stress free, shaped, diamond powder coatings can be electrophoretically deposited in a relatively short amounts of time. These diamond powder precursor coatings are then densified in a hot filament assisted CVD reactor to produce good quality CVD diamond/diamond powder composites. This combination of deposition techniques avoids many potential problems associated with predominantly CVD diamond.
