    Abstract: A method of producing an abrasive product consists of providing a mixture of a mass of discrete carbide particles and a mass of cubic boron nitride particles, the cubic boron nitride particles being present in the mixture in an amount such that the cubic boron nitride content of the abrasive product is 25% or less by weight, and subjecting the mixture to elevated temperature and pressure conditions at which the cubic boron nitride is crystallographically stable and at which substantially no hexagonal boron nitride is formed, in the presence of a bonding metal or alloy capable of bonding the mixture into a coherent, sintered product, to form the abrasive product. The bonding metal or alloy comprises a combination of a transition metal or a transition alloy and up to 40% by volume of the bonding metal or alloy of a second metal which is a stronger nitride or boride former than the transition metal or the transition metal alloy.

    Abstract: A method for making a nickel/silicon sputter target, targets made thereby and sputtering processes using such targets. The method includes the step of blending molten nickel with sufficient molten silicon so that the blend may be cast to form an alloy containing no less than 4.5 wt.% silicon. Preferably, the cast ingot is then shaped by rolling it to form a plate having a desired thickness. Sputter targets so formed are capable of use in a conventional magnetron sputter process; that is, one can be positioned near a cathode in the presence of an electric potential difference and a magnetic field so as to induce sputtering of nickel ion from the sputter target onto the substrate.

    Abstract: Refractory metal/Si sputter targets and methods of preparing such targets are disclosed. The targets are made via atomization techniques wherein an inert gas stream impinges upon the requisite molten metals to form powder particles. The particles are pressure consolidated into the near net shape desired for a given target configuration. Ti/Si targets are preferred and are characterized by having low oxygen content on the order of about 50-1,000 ppm with an oxygen content of about 100-1,000 ppm being more preferred. These targets also have a grain size distribution wherein substantially all of the grains are less than 20 mu m in size. Sputtering of such targets minimizes the amount of harmful particulates formed on the sputter coated substrates.

    Abstract: A sintered material and the tough-coated hard powder (TCHP) to make such a material is comprised of core particles that consist essentially of a first metal compound having the formula MaXb. M is a metal selected from the group consisting of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, aluminum, boron and silicon while X represents one ormore elements selected from the group consisting of nitrogen, carbon, boron and oxygen. The letters a and b represent numbers greater than zero up to and including four. The core particles are surrounded by an intermediate layer consisting essentially of a second metal compound, different in composition from the first metal compound thereby forming coated particles. The material of the intermediate layer has a higher relative fracture toughness than the material comprising the core particles and is capable of bonding with the metal compound(s) forming the core particles and also being capable of bonding with iron, cobalt or nickel. The coated particles are surrounded by an outer layer of iron, cobalt, nickel, their alloys, their mixtures and their intermetallic compounds. The intimate liaison of multiproperty alloys within the TCHP grains allows the combination of normally conflicting sintered article performance characteristics (e.g., strength and hardness) at levels heretofore unseen in the powder metallurgical art.

    Abstract: An improved hard wearing surface zone is being formed in a tungsten carbide-cobalt cemented carbide. This has been achieved by a post-sintering heat treatment in a boron nitride containing environment of a hard metal of a suitable composition. The effect is most pronounced when the heat treatment is made of a hard metal which has previously been sintered to achieve a high carbon content through a suitable choice of chemical composition and processing conditions.

    Abstract: The method and composite of the present invention has a significant advantage over known composites in the size of the diamond particles contained therein. Without a change in the diamond/metal ratio, the larger size diamond particles (about 110 microns and about 160 microns in size) provide a composite (20) of increased thermal conductivity without sacrificing CTE. Thus the CTE of the composite (20) may be matched with the CTE of the electrical components (18) with which it is associated and still retain the advantages of high conductivity. While exemplary embodiments of the present invention have been described, it is to be understood that the embodiments described are illustrative only and the scope of the invention is to be defined solely by the appended claims when accorded a full range of equivalence, many variations and modifications naturally occuring to those skilled in the art from a perusal hereof.
