摘要： PURPOSE:To form a diamond thin film having excellent adhesivity to the substrate and high density and hardness, by evaporating carbon from a carbon- containing evaporation source to a substrate, and irradiating the substrate with accelerated ion seed simultaneously or alternately to the evaporation. CONSTITUTION:A substrate 7 made of ceramics, carbide alloy, thermet, various metals and alloys, etc. is attached to a holder 8 and placed in a reaction chamber 5 connected with a vacuum pump 6. An evaporation source such as amorphous carbon, graphite, diamond, etc. is heated with an evaporation apparatus 10 using an electron beam, etc. to evaporate the carbon to said substrate 7. On the other hand, N2 etc. is supplied through a leak valve 1, ionized to N ion by the ion source 2, passed through the accelerator 3, the analyzing magnet 4, and the ion accumulation lens 9, and radiated to the evaporation layer simultaneously or alternately to the evaporation process. A diamond carbon and/or a diamond thin film is formed on the substrate by this process. A thin film having the highest characteristics can be produced when the ratio of th atomic number of the evaporated atom to the charge number of the ion is 0.1-5 and the acceleration energy of the ion is 6-60keV per atom.

摘要： PURPOSE:To form easily various kinds of hard films on a substrate by using a laser vapor deposition installation by using graphite, carbon, metal, alloy, metallic compd., ceramics, etc. for forming a rotating body on which convergent laser light is irradiated. CONSTITUTION:Convergent laser light is irradiated on a rotating body under rotation in a vessel and the particles evaporating from the rotating body are deposited on a substrate, thereby forming a hard film thereon. The rotating body is made of a mixture composed of >=2 different materials selected from graphite, carbon, metal, alloy, metallic compd. and ceramics. The construction thereof is columnar, cylindrical body, conical body, disk body, and ring body. If such rotating body is formed of a powder mixture composed of, for example, metallic titanium and carbon, the hard film of titanium carbide can be formed on the substrate. The dense, strong and hard film is formed on the substrate with good adhesion at a high deposition rate by the above-mentioned method.

摘要： PURPOSE:To form a hard film having strong adhesive force with the surface of a substrate at a high deposition speed by a method wherein an ion plating method and an ion mixing method are conjointly used. CONSTITUTION:A film forming substance is coated on the surface of a substrate using an ion plating method, and non-metallic ions are implanted simultaneously or alternately on the above-mentioned film. To be more precise, when non-metallic ions are made to irradiate on the surface of the film while the formation of said film on the substrate surface is started using an ion-plating method and the film is grown in the range of thickness with which the effect of ion mixing can be obtained, the adhesive strength between the substrate and the film is strengthened and the film is firmly adhered to the substrate. Subsequently, when the desired film forming substance is deposited on the film by performing an ion plating method, the desired film can be formed on said film at a high deposition speed.

摘要： PROBLEM TO BE SOLVED: To offer a shot-peening material such that the maximum of the compressive residual stress is generated on the surface of a work to be processed without requiring roughing of the surface of the work by forming the shot- peening material from an inorganic substance having a certain specific gravity in the form of spheres whose mean diameter lies below the specified value. SOLUTION: A blasting material for shot-peening is made of an inorganic substance, whose specific gravity should preferably range between 16 and 20. Below 16 offers difficulty in giving a sufficient compressive residual stress to the surface of a work to be processed, depending upon the material of the work-exceeding 20 is unlikely to provide a strength suitable for blasting material, which requires use of a material of noble metal series to result in a very high cost. The spherical shape may be otherwise substantially, for example, a columnar with edges rounded or elliptical like a rugby ball. The mean diameter should lie below 1mm.

摘要： PROBLEM TO BE SOLVED: To prolong the lifetime of a blasting material having a certain specific gravity to a great extent and reduce the running cost by accelerating the blasting material to a desired speed, and allowing the material to collide against the work to be processed. SOLUTION: A speed of a blasting material for roughing the surface of a work to be processed should range between 10 and 40m/sec. For suppressing the exhausting of the material, a lower blasting speed is preferable for roughing the surface, however, a speed to some degree is required depending upon the material of the work. Therefore, a min. speed of 10m/sec will be required, while a blasting speed exceeding 40m/sec may generate a problem of shortening of the lifetime of the blasting material. A favorable specific gravity of blasting material ranges between 11 and 20-exceeding 20 offers difficulty in manufacturing the material according to the conventional technique to result in increase in the manufacturing costs. The favorable hardness of the work to be processed is under HV250.

摘要： PURPOSE: To provide a sintered body for a tool or the like having superior hardness, wear resistance and toughness by combining a binding phase of a metal, an alloy or a metallic compound with a specified volume percentage of a hard phase of polycrystalline diamond or cubic boron nitride.
CONSTITUTION: This sintered body consists of 20W70vol% continuous hard phase of polycrystalline diamond and/or cubic boron nitride and a binding phase of one or more kinds of components selected among metals, alloys and metallic compounds. Powder or granules of one or more kinds of components for the binding phase are coated with layers of diamond and/or cubic boron nitride by plasma chemical vapor deposition, and the resulting composite powder or granules are sintered to obtain the sintered body. Since the hard phase in the sintered body is continuous and envelops the binding phase as the core material, the hardness of the sintered body is high as a whole, and at the same time, the toughness of the core material is effectively developed.
