  • Metal powders, such as Fe, Cu, Sn and WC, were used to prepare metal bond by conventional and microwave pressureless-sintering. The effects of different sintering processes on the densification and impact toughness of metal bonds were studied. SEM was used to observe the microstructure of the bond. Research indicates that compared with conventional pressureless sintering, microwave pressureless sintering improves the relative density and mechanical properties of the metal bond. The relative density and bending strength of the two bonds both reach the maximum at 900℃, which is 90.6%, 93.9% and 753 MPa, 816 MPa, respectively. It can be seen from the microstructure that microwave pressureless sintering can make the elements uniformly distributed and reduce the porosity of the bond. In addition, at the same level of performance, microwave pressureless sintering can reduce sintering temperature, thus effectively avoiding its damages to diamond strength.
