And Performance

The paper presents the research results on the structure and performance characteristics improvement of WC-Co hard-alloy matrix samples formed via the methods of cold and further hot moulding for the diamond-bearing details of drilling tools. It is shown that applying vanadium-nitride in 3 % in the composition of 94WC-6Co source materials provides the increase of sample hardness from 22.8 to 34.2 hPa, the compressive and bending strength from 4800 to 5340 MPa and from 2200 to 2280 MPa correspondingly, as well as the decrease of wear intensity from 1710×10-6 to 5200×10-6 g/m. The effect of formation of fine-grained structure for WC−CoNbN hard-alloy matrix with improved mechanical and performance characteristics revealed in the study points to the necessity of their usage in the development of efficient tools for drilling of oil and gas wells.
