  • Method for soldering metals with superhard man-made materials
    Patent number: 4117968
    Abstract: This invention relates to methods for soldering metals to superhard man-made materials such as diamond, boron nitride and hexanite and to soldering agents therefore. A method is proposed which comprises applying a metallizing coating to the soldering surface of the materials based on diamond and/or boron nitride, the materials to be joined by soldering being exposed to a temperature sufficient to bring about adequate adhesion of the metallizing coating to the materials to be soldered, and subsequently soldering the metal with the material bearing the metallized coating by use of soldering agents featuring ductile properties and melting points in the range up to 1,000.degree. C, whereby, in accordance with the invention, the metallizing coating is constituted by metals showing high adhesive activity toward materials based on diamond and boron nitride and accounting for from 3.0 to 65 percent by weight of the coating and by metals showing poor oxidizability which account for the balance.

  • Method of producing aggregated abrasive grains
    Patent number: 4024675
    Abstract: A method of producing aggregated abrasive grains for cutting tools and the like, comprising sintering a mixture of abrasive material powders and metal or alloy powders together with 5 to 10% by weight of the metal powders of an adhesion-active agent, to obtain a cake which is subsequently crushed. The sintering takes place in a loose state so that the cake has a porous structure which by crushing forms aggregated abrasive grains which break along the voids.

  • Alloy for metallization and brazing of abrasive materials
    Patent number: 4009027
    Abstract: The herein-proposed alloy is characterized in that it contains apart from such known components as copper, tin, aluminium, cadmium, zinc, titanium, chromium, zirconium, manganese, molybdenum, tungsten, iron, cobalt and nickel also vanadium, niobium, tantalum and boron taken either separately or in combination, in an amount of 0.001 to 80 weight percent of the total weight of all the components thereof. The alloy is advantageous in possessing good technological characteristics, being resistant to oxidation at elevated temperatures, featuring good adhesion to all kinds of abrasive materials and giving strong brazing alloys and metallization coatings.
