Synthesis of B4C/Al-B4C/TiB2 Composite with a Two-Layer Structure
A two-layer structure composite based on B4C/Al-B4C/TiB2 was prepared using hot pressing and infiltration aluminum in vacuum. The results showed that the B4C porous layer in the two-layer preform looked like a three-dimensional network of interconnected capillaries which could promote the infiltration of liquid aluminum. In the B4C/TiB2 layer the TiB2 dispersed homogenously in B4C matrix. After infiltrating process the two-layer B4C/Al-B4C/TiB2 composite with good interfacial bonding was obtained.
