Abstract

989,251. Abrasive tools. FELDMUHLE A.G. Jan. 8, 1962 [Jan. 7, 1961], No. 709/62. Heading B3D. An abrasive tool having a working portion, of diamond particles embedded in a metallic bond, on a metallic support is made by applying to the support two or more superposed layers of lacquer containing pulverulent titanium and/or zirconium, all of which layers except the outermost layer have diamond particles incorporated therein, applying the metallic bond to the outermost layer, degassing the layers, and heating the layers under reduced pressure to a temperature above the melting point of the metallic bond. A layer of pulverulent titanium and/or zirconium, distributed in a lacquer, is applied to a steel or other metallic support. Before the lacquer completely dries out, diamond particles are applied to form a layer 0.2 to 0.3 mm. thick. With very fine particle sizes the diamond particles are incorporated in the lacquer. A further layer of pulverulent titanium and/or zirconium in lacquer is then applied. After drying, a soldering foil of a copper or other alloy or a soldering material in powder form is applied. After degassing at 10<SP>-3</SP> to 10<SP>-5</SP> mm. of mercury, the assembly is heated in a high-vacuum furnace to just above the melting point of the solder. The process may be repeated so as to increase the thickness of the diamond particle layer. Where a dense layer of diamond particles is not required, the diamond particles are diluted by other particles, preferably abrasive, e.g. silicon carbide, boron carbide or corundum. A 50-50 mixture is preferably used.
