Development of Diamond–Metal Compositions for Diamond Tools

A technology that allows one to create new diamond–metal compositions for stone-cutting diamond tools is proposed, which is based on selecting new metallic binders with the use of powders of tailings (crushed samples of tungsten carbide and cobalt) of Tyrnyauz Tungsten–Molybdenum Plant and black tailings of Pobedit plant with almost the same composition. The proposed technology substantially increases the efficiency of diamond–metal compositions. The addition of powders of Tyrnyauz Tungsten–Molybdenum Plant or their mixtures with powders of black tailings of Pobedit plant to the blend provides finer porosity and increases the durability of diamond tools.
