Abstract

The structural alterations in the diamond–metallic binder transition zone in the diamond(78.4Co–11.76Cu–7.84Sn–2CrB2) composite upon its sintering in a mold in hydrogen atmosphere at 800°C for 1 h have studied versus the hot re-pressing parameters, and the influence of such alterations on physical-mechanical and tribological properties of the composites has been clarified. Adding 2 wt % CrB2 to the starting diamond−(80Co–12Cu–8Sn) composite is shown to raise the ultimate compression strength from 816 to 1720 MPa, bending strength from 790 to 1250 MPa, and wear resistance by a factor of 2.4. The improvement of properties of the composite and the increase of its wear resistance are provided due to the formation of Cr3C2 nanocarbide in the transition zone and the uniform distribution of Co, CrB2 phases and CoSn inclusions in the volume of the metallic binder.
