ABSTRACT:
Composite materials are in the form of particles, such as bits and short filaments, and combinations of such particles with matrix materials forming high strength, wear and corrosion resistant materials and may be shaped to define cutting tools, dies, mold components, electrodes, bearing components, finishing tools and the like. Structures include substrates and synthetic diamond particles encapsulated therein or bonded thereto have superior grinding, cutting and finishing characteristics. Particles are in the form of microbits, spheroids, single crystals, short narrow filaments and metal whiskers coated with synthetic diamond formed with a core of graphite, metal, metal compounds, metal alloys, ceramic, cermet, glass and composites thereof. Filaments and bits are coated with a lubricating film of wear resistant metal. Methods for producing such composite synthetic materials include the chemical vapor-deposition of carbon atoms from hydrocarbon gas molecules in a high intensity radiation field such as a microwave energy field.
