Fabrication and Mechanical Properties of B4C/BN Laminated Ceramics

Abstract:

Article Preview

The B4C/BN laminated ceramics were prepared by tape casting/coating. The effect of structure on the mechanical behavior of the B4C/BN was studied. The results showed that the fracture toughness and bending strength are optimal when the layer thickness ratio (eB4C/eBN) is 15. The SEM photographs of B4C/BN laminated ceramic indicated that the high fracture energy mainly resulting from crack deflection and crack delamination at the BN weak interface.
