Abstract

1440401 Abrasive tools VSESOJUZ NI I PROEKT INST TUGOPLAVKIKH METALLOV I TVERDYKH SPLAVOV 3 Jan 1974 [3 Jan 1973] 00317/74 Heading B3D [Also in Division E1] A rock drill bit 1 has a working head 2 including fine abrasive grains 4 occupying an intermediate metallic layer 3 and coarse abrasive grains 7 occupying the intermediate layer and an outer metallic layer 5 free of fine abrasive grains, the inner metallic layer 8 also being free of fine abrasive grins. Each of the coarse grains has ¢-<SP>2</SP>/ 3 of its volume disposed in the intermediate layer and the remainder in the outer layer. Suggested compositions for the layers 3, 5, 8 include (a) nickel, iron and tungsten carbide and (b) tungsten-carbide and cobalt, and it is stated that in making the working head in a graphite mould the layers are impregnated with melts of copper, copper and nickel, copper with nickel and zinc or copper, silver and zinc after they have been pressed. The coarse abrasive grains may be of, e.g. natural or synthetic diamond or cubic boron nitride and are 1-2À5 mm. in size and the fine abrasive grains may be of like materials to the coarse grains or of tungsten carbide and are 50-800 microns in size. Layers 3, 5 normally have a combined thickness equal to the size of the coarse grains.
