Abstract
Microstructures and mechanical properties of spark plasma sintered (SPS) Al2O3-Co composites were investigated depending on the sintering temperatures (900–1200°C) and cobalt contents (0∼12 mass%). The material properties of relative density and fracture toughness increased as the sintering temperature and Co content (up to 12 mass%Co) increased. In the SPSed Al2O3-Co composite sintered at 1200°C, maximum values of relative density and fracture toughness about 99.3% and 8.1 MPam1⁄2, respectively were obtained. The fracture morphology of SPSed Al2O3-12 mass%Co composite showed a semi-brittle fracture mode due to the homogeneous dispersion of fine-sized Co particles.
