摘 要：We proposed a new method, electroplating followed by spark plasma sintering（SPS）, to fabricate laminated TiB2-B4 C/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-B4 C composites simultaneously. A flexural strength and fracture toughness of 651 MPa and 11.6 MPam1/2 respectively,are achieved, an approximately 90% improvement over TiB2-B4 C bulk.
