| Popis: | The results of studies aimed at improving the structure and performance characteristics of carbide matrices WC-Co samples, formed by cold pressing and thereafter hot pressing, for drilling tools diamond-containing materials. It is shown that the introduction of vanadium nitride in an amount of 3% into the composition of the starting materials 94WC-6Co provides an increase in the hardness of the sample from 22.8 to 34.2 GPa, the strength limit in compression from 4800 to 5340 MPa and bending from 2200 to 2280 MPa, as well as reduction of wear intensity from 1710×10-6 to 5200×10-6 g/m. The revealed effect of the formation of a fine-grained structure of a carbide matrix WC-Co-VN with increased mechanical and operational characteristics indicates the need for their use in the development of effective tools for drilling oil and gas wells. |
