The work is devoted to increasing the service life of PDC bits when drilling rocks alternating in hardness by equipping tools with additional superhard elements. Experimental data have shown (ISM NAS (Ukraine)) that superhard elements have the following composition: diamond, tungsten carbide, cobalt, chromium diboride and zirconium dioxide, and the latter two components are included in the composite in a ratio of 2:4. Inserts made of a new composite have minimal cracking, increased wear resistance and cutting abil...
