Abstract:
A new family of cobalt-free premixed materials for diamond cutting tools was developed as an alternative to both pure cobalt and “prealloyed” powders. This product family was designed to combine high mechanical properties with the compressibility and process simplicity intrinsic to the premixed approach. Hot pressing results are herein presented for several grades and compared to their free sintering performance. Influence of main processing parameters and their impact on physical and mechanical properties is discussed. The matrix interaction with synthetic diamonds and its degree of metallurgical bonding is studied as well, on both a qualitative and quantitative basis.
