Superhard Abrasive Composite Powders Produced from Diamond and Cubic Boron Nitride with a Carbon Binder

摘要

The results of research aimed at developing superhard abrasive composites from starting diamond and cubic boron nitride powders with a carbon binder are presented. The materials were produced at subatmospheric pressure with the formation of condensed carbon released in the decomposition of hydrocarbons (at T = 1273-1523 K). The use of these materials as polycrystalline granules (particles) is effective for the production of grinding and polishing tools with improved performances.
