Abstract: | Conclusion Ceramic-cemented carbide compact inserts have been developed by hot-pressing sintering techniques, the upper part of the compact
insert is of Al2O3 + TiB2 ceramic material, while the base part of the compact insert is of WC + Co cemented carbide. The compact insert makes full
use of the advantages of the high hardness of ceramic materials and the high strength of cemented carbide, and its mechanical
properties are just between that of Al2O3 + TiB2 and WC + Co. SEM, XRD and electron microprobe analysis showed that element diffusion and formation of new phases are the
main causes for the bond of Al2O3 + TiB2 with WC + Co in the interface. |
