Summary

Electrodischarge-machinable Al2O3-SiC-TiC composites exhibits a high fracture toughness, 9.6 ± 0.6 MPam1/2, as measured by indentation techniques, and a Vickers hardness of 20.3 ± 0.6 GPa. The composite's resistance to solid-particle erosion was measured for 143-m̈m-diameter SiC particles impacting at angles between 20 and 90° and at velocities of 50 to 100 m/s. The erosion rate exhibited a maximum for normal incidence, and the erosion resistance was better than that of commercial Al2O3. Scanning electron microscopy indicated that material wastage occurred by a combination of brittle fracture and microplasticity.
