Fabrication and Mechanical Properties of Nano-Al2O3 Based Composite Ceramic Tool Material

Abstract:

Article Preview

The Al2O3(nm)/SiC(μm)/Al2O3(μm)ceramic tool materials were fabricated by the hot-pressing technique. Effect of the compositions on microstructure and mechanical properties is investigated. With nano-particles content decreasing, the flexural strength increased and fine grains can be obtained. When the nano-alumina content is 60wt%, the grain of this sample is fine, the Vickers hardness and flexural strength are 16.24 GPa and 678 MPa, respectively.
