Title:
COMPOSITE MATERIAL FOR DRILLING APPLICATIONS
Document Type and Number:
WIPO Patent Application WO2004111284
Kind Code:
A3
Abstract:
A composite material consists of a plurality of cores dispersed in a matrix. The cores are formed of ultra-hard material, or the components for making an ultra-hard material. The matrix is formed of the components for making an ultra-hard material of a grade different to that of the cores, and a suitable binder. The ultra-hard material is polycrystalline in nature and is typically PCD or PcBN. The cores are typically provided as granules coated with the components for making an ultra-hard material and the binder. The composite material typically takes on a honeycomb structure of an ultra-hard material and cores within the pores of the honeycomb structure bonded to the honeycomb structure. The pores of the honeycomb structure may be ordered or random.
