The Impact of Production Conditions on the Properties of Diamond-Abrasive Composites with a Matrix of Iron-Carbon Alloys

Abstract

Diamond-metal powder mixtures obtained by explosive pressing with subsequent heat treatment of the compacts are studied. It is shown that the use of the energy of explosion at the stage of powder molding shows good returns in production of high-performance diamond-materials, including, but not limited to that on widespread iron-carbon binders. A specific character of the explosive impact results in activation of the material of the binder which then comes out in intensive hardening upon further high temperature treatment. Shock waves provide favorable thermobaric conditions which ensure better integrity of the diamond component compared to that provided by conventional sintering methods. We obtained the samples of abrasive diamond composites with a wear resistance corresponding to the level of wear resistance of industrial diamond pencils, consumption of rough diamonds being twice as low.
