Abstract
In depositing an adhering, continuous, polycrystalline diamond film on a substrate by forming a refractory nitride interlayer on the substrate and depositing diamond on the interlayer in a vacuum chamber containing a microwave activated mixture of hydrogen and a gas including carbon, the crystal orientation of the deposited diamond, <111> or <100>, is selected by controlling the pressure in the chamber. Preferably, relatively higher microwave power is utilized at higher pressures.
