Алмазный поликристаллический композиционный материал для оснащения бурового инструмента

Abstract

The structure, strength, hardness and wear resistance of composite materials received under high pressure andhigh temperature in Cdiam+Co+WC and Cdiam+Co+Ni+WC in Nb-screen were considered. The most highest mechanical characteristics were obtained under sintering of the composite additionally containing Ni.
