Abstract
An adhering, continuous, polycrystalline diamond film is deposited on a z sulfide substrate by forming a refractory nitride interlayer directly on the substrate and then depositing diamond on the interlayer in a vacuum chamber containing a microwave activated mixture of hydrogen and a gas including carbon. The diamond film may be of optical quality and may be deposited without mechanical treatment or seeding of the zinc sulfide substrate or the nitride interlayer. However, diamond deposition may be facilitated by abrasion of the interlayer before diamond deposition.
