    摘要： A superhard material-metal composite product comprises a plurality of metal coated superhard particles (diamond or cubic boron nitride), and a binder alloy forming a cementing matrix which binds the coated superhard particles into a coherent mass. The binder alloy has a melting point below about 1300.degree. C. and is capable of wetting the metal coating on the superhard particles. The superhard material-metal composite product is formed by assembling the coated particles and the binder alloy in a graphite mold, and then hot pressing at temperatures and pressures well below the temperatures and pressures of the diamond forming region. The superhard component comprises about 40% to 75% by volume of the composite product. The superhard material-metal composite product is of intermediate quality and is particularly useful in earth boring bits for drilling soft rock formations having abrasive rock stringers therein.

    摘要： A hot bar apparatus for effecting solder bonds for high density electronic components has a diamond or diamond-like (i.e. a generally diamond crystal lattice with graphite impurities) surface that makes contact with the leads of the electronic component and transmits the heat necessary to effect a solder bond. The diamond or diamond-like surface has superior wear characteristics over any other material, and it also is an electrical insulator to protect the electronic components from spurious voltages and currents generated by electrical currents that provide the heat for the hot bar.

    摘要： A diamond element having good bonding properties and a method for fabricating the diamond element in which a diamond substrate is coated by and bonded to a first layer of chromium carbide, a second layer containing titanium, vanadium, zirconium, niobium, tantalum, iron, cobalt, nickel or copper, is bonded to said first layer, and a third layer of tungsten, or molybdenum deposited by a CVD technique utilizing metal halides, is bonded to said second layer. The second layer functions to protect the chromium carbide layer against attack by halide containing gas during the CVD deposition of the tungsten, or molybdenum.

    摘要： Superabrasive cutting elements, backed compacts and methods for their manufacture are disclosed wherein metal coated superabrasive particles are cemented under HPHT conditions. The superabrasives bond to the metal of the coating and the metal coatings of adjacent particles bond to each other forming a matrix. A binding aid with thermal expansion characteristics close to that of the superabrasive particle can be infiltrated through or otherwise mixed with the particles to assist in the bonding between the metal coatings and to fill in voids. Catalyst and non-catalyst binding aids can also be used. Uncoated, smaller superabrasive particles can be interstitially dispersed among the coated particles to increase the superabrasive concentration and can self bond to form a cemented/sintered structure. Tungsten is a preferred metal coating and silicon is a preferred binding/sintering aid. The superabrasive can be diamond, cubic boron nitride, boron doped diamond or crushed sintered polycrystalline aggregates. The free-standing cutting element can have a brazeable layer and the compact can be backed with, for example, cemented tungsten carbide. Free-standing cutting elements can be thermally stable up to 1,200.degree. C. Backed compacts can be thermally stable up to 1,100.degree. C.
