摘要

We proposed a new method,electroplating followed by spark plasma sintering (SPS),to fabricate laminated TiB2-B4C/Cu-Ni composites with high strength and high toughness.It is found that a thin intermediate Cu layer can effectively enhance the strength of the interface between the ceramics and the metals,resulting in a high flexural strength and toughness of the laminated TiB2-B4C composites simultaneously.A flexural strength and fracture toughness of 651 MPa and 11.6 MPa m1/2 respectively,are achieved,an approximately 90％ improvement over TiB2-B4C bulk.
