    摘要: A DC plasma jet method enables us to synthesize diamond at a high speed by spraying an activated carbon-containing gas as a plasma jet to a substrate. Despite the high speed deposition, the method cannot synthesize a wide uniform diamond owing to the ununiformity of the jet and the restriction of sizes of torches. Uniform deposition of diamond on a wide substrate is a purpose of this invention.More than two anode-nozzles and more than one plasma torch are utilized. They are disposed with their center lines crossing at a point. An inert gas or hydrogen gas are supplied in the torches in order to excite inner arc plasma jets. Then the torches are applied a negative DC voltage. The anode-nozzles are applied a positive voltage and are supplied with an inert gas, hydrogen gas or both an inert gas and hydrogen gas. Outer transferable plasma jets are formed between the cathodes of torches as cathodes and the nozzles as anodes. The plasma arc jets are integrated into a unified plasma flame. The nozzles and the torches are moved or rotated in order to enlarge the plasma formation areas. A carbon-containing gas is supplied to confluences of the plasma jets from the cathode-torches and the anode-nozzles from gas supplying nozzles.

    摘要: A bonding tool has a head portion made essentially of vapor-deposited diamond, wherein a principal diamond crystal plane forming a head face is a (111) plane. Such a head face has high hardness and a good wear resistance. In order to improve the toughness of a bonding head which is mainly made of vapor-deposited diamond, a portion or ply forming the head face consists essentially of high-purity diamond, and another portion or ply supporting the head face consists essentially of low-purity diamond. The head face has a high rigidity, while the portion supporting the head face has a high toughness. In order to provide a bonding head portion which is mainly made of vapor-deposited diamond with electrical conductivity, a first portion or ply forming a head face consists essentially of polycrystalline diamond containing a relatively small amount of dopant, and another portion or ply supporting the first portion or ply contains a large amount of dopant. The head portion having electrical conductivity can be heated by energization. In a tool employing a coating containing vapor-deposited diamond as a bonding head portion, the coating is formed by a compound of a metal or ceramics and vapor-deposited diamond, in order to improve the strength of the coating and adhesion to a tool substrate.

    摘要: No wide bulk diamond wafer exists at present. A wide diamond-coated wafer is proposed instead of the bulk diamond wafer. Diamond is heteroepitaxially deposited on a convex-distorted non-diamond single crystal substrate by a vapor phase deposition method. In an early step, a negative bias is applied to the substrate. In the case of a Si substrate, an intermediate layer of .beta.-SiC is first deposited on the Si substrate by supplying a low carbon concentration material gas. Then the carbon concentration is raised for making a diamond film. The convex-distorted wafer is stuck to a holder having a shaft which is capable of inclining to the holder. The wafer is pushed to a turn-table of a polishing machine. The convex diamond wafer can fully be polished by inclining the holder to the shaft. A wide distorted mirror wafer of diamond is produced. Fine wire patterns can be made on the diamond mirror wafer by the photolithography.

    摘要: A diamond cutting tool has a tool substrate and a cutting edge member. The cutting edge member is formed of a material having a three-layer structure or a diamond composite material. When the material having a three-layer structure is employed, the cutting edge member is formed by a vapor-deposited diamond layer defining a rake face, a layer of a composite material of vapor-deposited diamond and a metal or ceramics, and a layer of the metal or ceramics. The metal is prepared from Mo, W, Cr, V, Nb, Ta, Co, Ni or Fe, while the ceramics is prepared from cBN, SiC, Si.sub.3 N.sub.4, WC, TiC, TaC, NbC, Cr.sub.3 C.sub.2, Mo.sub.2 C, VC, TiN or BN. The cutting edge member is brazed to the tool substrate through the metal or ceramics layer. When the diamond composite material is employed, on the other hand, the cutting edge member is formed of a composite material of particles or fibers of AlN, cBN or SiC and vapor-deposited diamond. The diamond cutting tool is excellent in heat resistance and durability.
